The electrical generation of spin current is one of the most important topics in spintronics. Recently, ferromagnet has drawn much attention as a spin current source because magnetization offers controllability of spin polarization direction. Here, we detect the spin current owing to the planar Hall effect, which has hardly been investigated ever, by means of the unidirectional magnetoresistance.
