Spintronics is a critical technology for magnetic information storage including hard-disk drives that underpin cloud computing and magnetic random access memory, MRAM for wider electronic memory applications. Spintronics describes the broad range of physics interactions between the spin component of electronic currents and the magnetization in multilayered thin-film systems. This experimental project aims to investigate the physics needed to effectively control spin current transport for the development of more energy efficient applications in spintronics. One aim is to combine metallic and semiconducting thin films to investigate gated spin-current control. The specific focus is an investigation to understand the physical basis of the efficiency, effectiveness and functional constraints of damping and data writing in spintronic structures using field, spin-transfer torque or spin-orbit torque switching and damping mechanisms.

自旋电子学是磁性信息存储的关键技术，包括支撑云计算的硬盘驱动器和磁性随机存取存储器，用于更广泛的电子存储器应用的MRAM。自旋电子学描述了多层薄膜系统中电子流的自旋分量与磁化强度之间的广泛物理相互作用。这个实验项目旨在研究有效控制自旋电流传输所需的物理学，以开发自旋电子学中更节能的应用。一个目标是将联合收割机金属和半导体薄膜结合起来研究门控自旋电流控制。具体的重点是调查，以了解使用场，自旋转移扭矩或自旋轨道扭矩切换和阻尼机制的自旋电子结构中的阻尼和数据写入的效率，有效性和功能约束的物理基础。
