A large perpendicular anisotropic magnetoresistance (AMR) is obtained in a MgO/Fe/Cu heterostructure, with a maximum AMR ratio of 0.59%. The perpendicular AMR is approximately inversely dependent on the thickness of the Fe layer above 2.5 nm. It can be increased by enhanced structural asymmetry, which implies an interface effect mainly derived from interfacial Rashba spin-orbit scattering in the MgO/Fe/Cu...
Yttrium iron garnet (YIG) has been widely used in spin wave studies thanks to its low Gilbert damping constant. However, most high-quality YIG films are grown on gadolinium gallium garnet (GGG) substrate, which makes it difficult to integrate with existing semiconductor technology. We show spin wave excitation in a nanometer-thick YIG micro-channel on silicon substrate. The YIG is grown by pulsed...
