Understanding the Spin Current Hermitivity in Ferromagnet Bilayers
ORAL
Abstract
The effervescent area of spintronics has produced different fields of research; among them is the field of interface phenomena capable of revealing the most intriguing effects of quantum mechanics. In this work, we study the phenomenon of spin current hermitility in ferromagnet bilayers, 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. We performed this observation on permalloy/cobalt bilayers and other ferromagnet bilayers [1].
