横向配置的铁磁/无磁多端自旋电子器件使详细研究非磁体中的自旋积累成为可能。利用非局域自旋注入技术研究了横向结构中的自旋扩散过程。基于自旋电阻的概念，通过优化探头结构和结结构，实现了有效的自旋注入和检测。利用非局域自旋注入诱导的有效自旋电流吸收行为，最终实现了纳米铁磁体的磁化转换。
Laterally configured ferromagnetic/nonmagnetic multi-terminal spintronic devices enable the performance of detailed study of spin accumulation in nonmagnets. The spin diffusion processes in lateral structures are investigated using nonlocal spin injection techniques. Efficient spin injection and detection are accomplished by optimizing the probe configuration and junction structures on the basis of the concept of spin resistance. The magnetization switching of a nanoscale ferromagnet is finally realized using efficient spin current absorption behaviour induced by nonlocal spin injection.
