Interfacial and bulk spin Hall contributions to field-like spin-orbit torque generated by Iridium
Sutapa Dutta, Arnab Bose, A. A. Tulapurkar +2
We present measurements of spin orbit torques generated by Ir as a function of film thickness in sputtered Ir/CoFeB and Ir/Co samples. We find that Ir provides a damping-like compo…
Sign reversal of field like spin-orbit torque in ultrathin Chromium/Nickel bilayer
Arnab Bose, Hanuman Singh, Swapnil Bhuktare +2
In this work report unconventional sign change of field like spin orbit torque in ultra-thin Chromium(1.5nm-5nm)/Nickel(8nm) bi-layer. We performed standard spin-torque ferromagnet…
Observation of anomalous spin-torque generated by a ferromagnet
Arnab Bose, Duc Duong Lam, Swapnil Bhuktare +4
In this work we report observation of in-plane current induced out-of-plane magnetic field driven torque in spin valve structure. Since ferromagnet has high spin orbit coupling it…
Observation of Spin Nernst effect in Platinum
Arnab Bose, Swapnil Bhuktare, Hanuman Singh +2
Central focus of spintronics is concentrated on generation of pure spin current and associated spin torque. Pure spin current can be generated by spin Hall effect in heavy metals b…
