  • Nanomagnetic materials allow for the emission and detection of microwave radiation in technological applications by spin excitation. Here, the authors present sensitive room-temperature microwave detectors based on nanoscale magnetic tunnel junctions, enabled via spin torque and injection locking.

  • An anomalous Hall spin current in a ferromagnetic conductor generates a giant spin–orbit torque with unique angular symmetry. This discovery enables a spin torque nano-oscillator with potential applications in neuromorphic signal processing.

  • Harvesting ohmic heat for signal processing is one of major challenges in modern electronics and spin caloritronics, but not yet well accomplished. Here the authors demonstrate a spin torque oscillator device driven by pure spin current arising from thermal gradient across an Y3Fe5O12/Pt interface.

  • Energy-efficient manipulation of spins at the nanoscale can advance magnetic storage and computing technologies. Here the authors show that low-dimensional chaos generated by alternating spin torque can induce magnetic switching in a nanoscale ferromagnet.

  • In ferromagnetic thin films, spin torque applied to nanometre-scale areas excites localized magnetic self-oscillations, or reduces net magnetization if applied uniformly. Here, Duan et al.show how 1D geometrical confinement allows for coherent self-oscillations to be excited over extended length scales.

  • Magnetic oscillators with easy plane magnetic anisotropy hold promise for spintronic applications as nanoscale microwave generators, sources of spin supercurrents and ultrafast spiking neurons. The authors report the experimental realization of an easy-plane ferromagnetic spin-Hall oscillator, where the magnetization exhibits persistent auto-oscillations with a very large precession cone angle.

  • Spin-orbit torque driven oscillators, such as spin Hall oscillators, form a class of devices that are intensively studied due to potential practical applications in spintronics. Here, the authors modify the conventional ferromagnetic/nonmagnetic stack to include an additional ferromagnetic layer and leverage the giant magnetoresistance effect to enhance the direct conversion of an in-plane driving current into the microwave output signal.
