Current-induced spin-orbit torque (SOT) is attracting increasing interest and exciting
significant research activity. We aim to provide a comprehensive review of recent progress in …

This paper reviews the state of the art in spin-torque and spin-Hall-effect-driven nano-
oscillators. After a brief introduction to the underlying physics, the authors discuss different …

The spin Hall effect in a non-magnetic metal with spin–orbit coupling injects transverse spin
currents into adjacent magnetic layers, where the resulting spin transfer torque can drive …

Magnetism is a very fascinating and dynamic field. Especially in the last 30 years, there have
been many major advances in a range of areas from novel fundamental phenomena to new …

Magnetic skyrmions are topologically non-trivial spin textures that manifest themselves as
quasiparticles in ferromagnetic thin films or noncentrosymmetric bulk materials. So far …

Recent advances in the studies of pure spin currents–flows of angular momentum (spin) not
accompanied by the electric currents–have opened new horizons for the emerging …

The synchronization of multiple nanocontact spin-torque oscillators (NC-STOs) is mediated
by propagating spin waves (SWs). Although it has been shown that the Oersted field …

Spin-orbit torque (SOT) can drive sustained spin wave (SW) auto-oscillations in a class of
emerging microwave devices known as spin Hall nano-oscillators (SHNOs), which have …

Spin–torque oscillators offer a unique combination of nanosize, ultrafast modulation rates
and ultrawide band signal generation from 100 MHz to close to 100 GHz. However, their low …

Spin Hall nano-oscillators (SHNOs) are an emerging class of pure spin current driven
microwave signal generators. Through the fabrication of 20 nm nano-constrictions in Pt/NiFe …
