Crystalline dependence of spin transmission in CrO thin films

Qin, J.*; Hou, D.*; Chen, Y.*; Saito, Eiji; Jin, X.*

Spin transmission in CrO films of different crystalline textures is studied experimentally. With YFeO $_{12}$ /CrO/Pt trilayer devices, a spin current is injected into CrO by spin pumping from YFeO $_{12}$ , and the spin transmission is monitored by the inverse spin Hall voltage ( $V_mathrm{ISHE}$ ) in Pt. For (0001) plane textured CrO films, $V_mathrm{ISHE}$ vanishes quickly below the Nel temperature. However, the $V_mathrm{ISHE}$ shows a broad shoulder below the Nel temperature for and plane co-textured CrO. Such a difference in the temperature dependence of CrO can be understood by the different Nel vector orientations with respect to the injected spin moment direction.
