Interfacial origin of unconventional spin-orbit torque in Py/$\gamma -$IrMn${}_3$

Akash Kumar, Pankhuri Gupta, Niru Chowdhury +6

Angle-resolved spin-torque ferromagnetic resonance measurements are carried out in heterostructures consisting of Py (Ni${}_{81}$Fe${}_{19}$) and a noncollinear antiferromagnetic quant…
