Spintronics phenomena of two-dimensional electron gas at oxide interfaces

Abstract

In addition to magnetism, superconductivity, quantum transport, and ferroelectricity, the tunable Rashba spin–orbit coupling from spatial inversion symmetry broken of 2-dimensional electron gas (2DEG) at oxide interfaces has been exploited to induce rich spin-dependent physical effects and has recently become the focus of intense interest. Here, we review the recent advances in this field, including spin–charge interconversion, spin–magnetization interaction, and spin texture. These properties are intriguing due to their potential to advance spintronics devices. All these intriguing properties not only hold great promise for 2DEG at oxide interfaces in spintronic devices but also further deepen our understanding of this frontier field.
