description

The spin Hall effect is a key element of various spintronics applications. Here, the authors study the orientation-dependent interconversion of spin and charge information in Co${}_{60}$Fe${}_{20}$B${}_{20}$. In a nonlocal magnon transport using Y${}_{3}$Fe${}_{5}$O${}_{12}$ as a spin conduit, the spin Hall effect amplitude depends on the relative alignment between the Y${}_{3}$Fe${}_{5}$O${}_{12}$ and Co${}_{60}$Fe${}_{20}$B${}_{20}$ magnetization vectors. In order to suppress direct magnonic contributions so as to study the electronic origin of this effect, Y${}_{3}$Fe${}_{5}$O${}_{12}$ and Co${}_{60}$Fe${}_{20}$B${}_{20}$ are exchange-decoupled by a Cu interlayer.
