Electromotive Force Generated by Spin Accumulation in FM/$n$-GaAs Heterostructures

Chad C. Geppert, Lee R. Wienkes, Kevin D. Christie +3

We report on a method of quantifying spin accumulation in Co${}_2$MnSi/$n$-GaAs and Fe/$n$-GaAs heterostructures using a non-magnetic probe. In the presence of a large non-equilibr…
