Spin transport in lateral ferromagnetic/nonmagnetic hybrid structures

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.
