Merging magnetism and superconductivity could enable loss‑free spin flow

Researchers from the University of British Columbia, Max Planck Institute for Solid State Research and University of Nevada have proposed a new class of quantum materials - superconducting altermagnets - that could carry persistent spin-polarized currents with zero dissipation, marking a potential breakthrough in superconducting spintronics. 

The team's theoretical study shows how these materials can host spin supercurrents that remain stable even in the presence of spin-orbit coupling (SOC) and magnetic disorder - conditions that usually extinguish spin transport in normal metals.

Spin-controlled photon emission in 2D perovskites enables quantum communication

A University of North Carolina at Chapel Hill research team has demonstrated a novel way to encode quantum information directly within the light produced by two-dimensional perovskites - opening a potential path to simpler, more efficient quantum communication systems. The study explores how spin dynamics in two-dimensional organic–inorganic hybrid perovskite (2D-OIHP) quantum wells can generate polarization-encoded photons suitable for secure communication protocols.

Two-dimensional perovskites are well known for their performance in light-emitting and photovoltaic devices, but the UNC team, led by Professor Andrew Moran, has shown they can also act as microscopic light sources whose intrinsic exciton spin behavior defines the polarization of emitted photons. When ultrafast laser pulses excite the material, they generate pairs of bound charge carriers - excitons - whose spins determine the polarization of emitted light.

Wafer-scale MoS₂ cuts surface damping in permalloy spintronic films

Researchers from The University of Manchester have discovered that interfacing magnetic thin films with atomically thin molybdenum disulfide (MoS₂) fundamentally alters how these films dissipate energy - a step toward practical, wafer‑scale 2D spintronic devices.

Using ferromagnetic resonance (FMR) spectroscopy, the team investigated spin pumping and damping mechanisms in large‑area transition‑metal dichalcogenide (TMD)-ferromagnet heterostructures, specifically MoS₂–Ni₀.₈Fe₀.₂ bilayers with varying ferromagnetic thickness. The MoS₂ was grown using chemical vapor deposition (CVD), an industry‑compatible approach that allows uniform monolayer and bilayer coverage across wafer‑scale samples.

Researchers demonstrate all-optical switching of spin–valley ferromagnetism in twisted MoTe₂

Researchers from ETH Zürich, University of Washington, University of Basel and National Institute for Materials Science have demonstrated all-optical control over the spin-valley polarization in twisted molybdenum ditelluride (t‑MoTe₂) homobilayers - a step toward dynamically reconfigurable quantum materials and optically defined topological circuits. The work shows how circularly polarized light can reversibly switch the magnetic orientation of a strongly correlated ferromagnetic state, all without changing the sample temperature.

The experiments, led by Prof. Ataç Imamoğlu (ETH Zürich), Prof. Tomasz Smoleński (University of Basel), and colleagues, exploit a system where two atomically thin MoTe₂ layers are stacked with a small twist angle. This twist creates a moiré superlattice with flat, valley‑contrasting Chern bands, giving rise to highly correlated quantum phases - including Chern insulators and ferromagnetic metals - depending on the electron filling. Because the electronic bands are nearly dispersionless, electron-electron interactions dominate, resulting in spontaneous spin alignment even at cryogenic but steady temperatures.

Twist-driven super-moiré skyrmions reach 300 nm in CrI₃

Researchers from the University of Stuttgart, University of Washington, University of Edinburgh, University of Waterloo, the National Institute for Materials Science, and Oak Ridge National Laboratory have demonstrated a new type of long‑range magnetic order in twisted double‑bilayer chromium triiodide (CrI₃). 

The study reports a “super‑moiré” magnetic state that extends far beyond the conventional moiré unit cell - highlighting twist angle as a powerful tool to engineer topological spin textures in 2D magnets.

Researchers demonstrate electrical control of 2D magnetism via ferroelectric switching

Researchers from the University of Maryland, King Abdullah University of Science and Technology (KAUST), Nankai University, Cornell University, University of Wisconsin–Madison, Oak Ridge National Laboratory, University of California, University of Tennessee, Air Force Research Laboratory and Rice University recently reported the first experimental realization of non-volatile, electrical control of magnetism in a two-dimensional (2D) material system. The collaborative work demonstrates a robust interferroic magnetoelectric coupling in a van der Waals heterostructure made of atomic layers of ferroelectric CuCrP₂S₆ and ferromagnetic Fe₃GeTe₂ - marking a milestone for 2D multiferroic research and energy-efficient spintronic applications.

At the heart of this work lies the long-standing challenge of stabilizing ferroic order in truly two-dimensional materials. While ferroelectric and ferromagnetic phenomena are both well-established in bulk materials, their coexistence in 2D is difficult to maintain due to depolarization fields and thermal fluctuations that destabilize long-range order. The team overcame these limitations by stacking exfoliated layers of the ferroelectric CuCrP₂S₆ and ferromagnetic Fe₃GeTe₂ with atomically clean interfaces, enabling short-range, interfacial coupling between their ferroic orders.

Intrinsic spin-triplet pairing indications found in NbRe superconductors

Researchers from Italy's Università degli Studi di Salerno, CNR-SPIN and the Norwegian University of Science and Technology (NTNU) recently found that the noncentrosymmetric superconductor niobium–rhenium (NbRe) could be the long-sought candidate for intrinsic spin-triplet pairing - a key ingredient for future superconducting spintronics and quantum computers.

Spin-triplet superconductors differ fundamentally from conventional “singlet” superconductors: their Cooper pairs carry spin as well as charge. This allows them to sustain spin-polarized supercurrents that can travel without resistance. Such a property would enable lossless spin transmission and stability in quantum information systems - a long-standing challenge in the field.

Topological nodal lines turn elemental cobalt into a room‑temperature spintronics platform

Researchers from Helmholtz-Zentrum Berlin für Materialien und Energie (HZB), Donostia International Physics Center, Leibniz Institute for Solid State and Materials Research Dresden and IMDEA Nanoscience have identified ferromagnetic hexagonal close-packed (hcp) cobalt as a prototypical magnetic nodal-line semimetal that remains robust at room temperature, turning a classic ferromagnet into a highly tunable topological platform for spintronics.

Cobalt has long been regarded as a textbook elemental ferromagnet with a supposedly well-understood band structure, examined in detail for over 40 years. Using spin- and angle-resolved photoemission spectroscopy (spin-ARPES) at the BESSY II synchrotron, the team now observes entangled, spin-polarized bands that cross along extended paths in momentum space without opening an energy gap, even at room temperature. These measurements reveal a dense network of magnetic nodal lines - topological band crossings between two spin-polarized states - that give rise to fast, robust charge carriers central to future information and spin-based technologies.

Researchers achieve field‑free switching of hard ferromagnets with giant spin‑orbit torque

Researchers at the University of Waterloo recently demonstrated fully electrical, field‑free control of perpendicular magnetization using spin‑orbit torque (SOT) in a low‑symmetry 2D magnet/topological‑insulator heterostructure, paving the way for scalable, energy‑efficient spintronic memory and logic devices.

Stacking the three-fold symmetry of BiSbTe on top of the two-fold symmetry of intercalated-CrTe, the interface only permits a unidirectional symmetry which produces an extremely strong out-of-plane spin torque and can deterministically switch a very hard, perpendicular magnet with ease.

Modern MRAM and related spintronic memories need dense, robust perpendicular magnetic anisotropy (PMA) bits that can be switched deterministically with low energy consumption, but conventional SOT easily switches only in‑plane moments and typically requires an external bias field to tilt perpendicular spins “up” or “down”. In perpendicular configurations, bits point out of the film plane, which boosts storage density but makes the energy‑efficient, fully electrical control of their state difficult. Standard heavy‑metal/ferromagnet stacks already break out‑of‑plane symmetry and can support in‑plane switching, yet deterministic out‑of‑plane reversal demands breaking additional in‑plane symmetries - usually via an applied magnetic field, which adds circuit complexity, power overhead, and risks cross‑talk between neighboring bits.
