More spin current can be produced with less energy lost at the source, thanks to inter-magnet pumping that rebalances angular momentum dissipation between sublattices in a ferrimagnetic multilayer.

Charge-transfer excitations, which define the optical bandgap in many insulators, also contribute to magnetic exchange in antiferromagnets. Femtosecond optical pumping of these transitions in canted antiferromagnet DyFeO₃ reshapes the spin-wave spectrum — the set of collective spin excitations that define the dynamics of the antiferromagnet — without destroying the long-range order.

This study reports real-space, layer-resolved magnetic imaging of the van der Waals antiferromagnet (Fe,Co)₃GaTe₂ using SPLEEM, revealing A-type interlayer coupling, intrinsic chiral spin textures and enabling controlled writing of antiferromagnetic skyrmions.

Researchers demonstrate field-free magnetisation switching in perpendicular magnetic anisotropy systems using spin reorientation and orbital Hall effects. This approach enables low power operation and scalable spintronic memory devices.

Spin light-emitting diodes convert electrically injected carrier spin into circularly polarized light. This Review highlights advances in spin injectors and emitter materials, and strategies for high electrically controlled polarization without magnetic fields for circular polarization-based spin-optoelectronic applications like optical communications.

The electrical generation of spin signals is of central interest for spintronics, where graphene stands as a relevant platform as its spin-orbit coupling (SOC) is tuned by proximity effects. Here, we propose spin-charge interconversion of maximal efficiency in graphene, obtained by adjusting the spin entanglement properties by tuning the SOC.

Nested skyrmion bags are topological magnetic structures with tunable topological charge that offer promise for spintronic devices. By combining micromagnetic simulations, Thiele equation analysis, and machine learning, the authors reveal the stability, current-driven dynamics, and efficient prediction of the skyrmion Hall angle in these structures, and demonstrate a proof-of-concept demultiplexer device.

Terahertz emission measurements challenge the prevailing view of long-range orbital transport

Quantum magnetometry on twisted CrI₃ reveals moiré magnetism characterized by a period that exceeds the underlying moiré superlattice by an order of magnitude.

Chiral phonons, quasiparticles of lattice vibrations arising from circular atomic motion, hold potential as carriers of angular momentum for next-generation technologies. Experiments show that they can generate orbital currents under thermal gradients.

A recently proposed class of magnets, so-called altermagnets, combine features of ferromagnets and antiferromagnets. We discuss the scientific appeal of altermagnets, current controversies and challenges for their practical use.
