  • Spin torques generated via the spin-Hall effect in CoFeB/W/MgO are found to stabilize magnetization in a high-energy anti-parallel state relative to an applied magnetic field. This observation serves as a platform for studying far-from-equilibrium spin dynamics and holds promise for realizing unconventional computing paradigms.

  • Electron spins in diamond allow magnetometry with high sensitivity, but the bandwidth in the microwave regime is limited to a narrow band around their resonance frequency. Here, the authors solve this problem by coupling the spins to a thin film of yttrium iron garnet, exploiting the non-linear spin-wave dynamics of the magnet.

  • Long-range spin transport is essential for spintronics applications, but so far has only been achieved in magnets below their Curie temperature. Here, the authors report on efficient spin transport in paramagnetic insulator Gd3Ga5O12 exposed to a moderate magnetic field exhibiting a spin diffusion length of 1.8 μm.

  • Observation of the entire dispersion relation for spin waves remains a challenge which prevents the full understanding of many intriguing magnetic properties. Here, the authors develop a table-top all-optical approach to map out the dispersion curve of pure-magnetostatic waves in magnetic films.

  • Ferrimagnets possess multiple spin sub-lattices resulting in a complex magnon band structure and subtle spin transport across interfaces. Here, the authors show how the spin Seebeck effect, the thermal generation of pure spin current, may be an effective tool to study these magnetic excitations.

  • Recently, significant progress has been made in higher harmonic generation of spin waves in magnetic materials, but it remains challenging to probe the coherence. Here, Lan, Liu et al observe the higher-harmonic spin-wave generation induced by static edge spin textures in a soft ferromagnetic film, and probe the coherence of higher harmonic generation.

  • Spin caloritronics focuses on the interaction of electron spins with heat currents. This Review describes newly discovered physical effects that have re-invigorated the field by stimulating further research into understanding the fundamentals of spin–phonon interactions, and providing new avenues to explore to improve current thermoelectric technology.
