Spin transistor in the EuO:Fe/GaAs contact

Abstract

Spin-wave structures with magnetic-field-driven current-voltage characteristics at room temperature were produced using a spintronic europium-monoxide-based thin-film emitter and a single-crystal n-GaAs semiconductor collector. This manifests practical implementation of the spin current transport and creation of a high-temperature spin transistor with the magnetic semiconductor/nonmagnetic semiconductor contact. © 2011 Pleiades Publishing, Ltd.
