Abstract

We report on measurements of direct spin Hall effect in a lightly n-doped GaAs channel with conductivity below 2000 Ω−1 m−1. As spin detecting contacts, we employed highly efficient ferromagnetic Fe/(Ga,Mn)As/GaAs Esaki diode structures. We investigate bias and temperature dependence of the measured spin Hall signal and evaluate the value of total spin Hall conductivity and its dependence on ...
