Abstract

We show electric field control of the spin accumulation at the interface of the oxide semiconductor Nb−SrTiO3 with Co/AlOx spin injection contacts at room temperature. The in-plane spin lifetime τ∥, as well as the ratio of the out-of-plane to in-plane spin lifetime τ⊥/τ∥, is manipulated by the built-in electric field at the semiconductor surface, without any additional gate contact. The origin of ...
