External driving of Rabi oscillations is a first step in the coherent manipulation of spin systems. Here the authors use ultrafast optical pulses to produce classical Rabi oscillations in ferromagnetic CoFeB, enabling the exploration of coherent phen

When interfaced with a current-carrying heavy metal, spin orbit effects can generate a torque on the magnetization of a ferromagnet, understood as a bulk effect. Here, the authors show evidence of an interfacial contribution to such spin orbit torque

The properties and characteristics of thin-film materials strongly depend on their textures and orientations. However, the attainable film morphologies are severely limited by substrates and growth thermodynamics. Metastable films that otherwise cann

We report on an experimental investigation of spin-orbit torque (SOT) in W(O)∣CoFeB heterostructures where a thin insertion layer with negligible spin-orbit coupling is inserted at the W(O)∣CoFeB interface. The SOT is found to be suppressed with

The velocity of domain walls driven by chiral spin-orbit torques is up to 10 times faster around right- than left-handed bends.
The use of current pulses to move domain walls along nanowires is one of the most exciting developments in spintronic
