Observation of Spin Current Hermiticity

Abstract

The spin Hall effect is one of the most relevant effects in spintronics and the key to conversion from charge current into spin current. We report here a phenomenon, which appears in response to the spin Hall effect and represents the anti-polarization of the spin current due to the coupling between interfacial magnetic anisotropies. Such an effect produces a Hermitian spin current. We realized experiments on permalloy (Py) and Cobalt (Co) bilayers to discuss this phenomenon.
