The spin generation in strong spin-orbit coupling systems has led to a large spin-orbit torque. Recently, the orbital generation in weak spin-orbit coupling systems was reported. In this study, we investigate the spin-orbit torque of a nonmagnet/ferromagnet bilayer, where the nonmagnet is Pt...
samples with Pt and Ta underlayers due to their opposite sign of the spin Hall angle7, which also proved that the spin-orbit torque is a function of the spin Hall angle8. On the other hand, the field-like torque induced by the Rashba effect due to structural asymmetry was also claimed ...

films result from the strong orbital magnetic moment, which has been observed by X-ray magnetic circular dichroism (XMCD) measurement. Thex-polarized spin torque efficiency reaches up to −0.083 and favors complete field-free switching of CoFeB magnetized along the in-plane charge current ...
Recent theory revealed that orbital Hall effect creates orbital current, which can be much larger than spin Hall-induced spin current. However, orbital current cannot directly exert a torque on a ferromagnet, requiring a conversion process from orbital current to spin current. Here, we report two...
