SPINTRONICS DEVICE, MAGNETIC MEMORY, AND ELECTRONIC APPARATUS

摘要

Provided are a spintronics device, a magnetic memory, and an electronic apparatus with which it is possible to generate a large spin current without depending on any specific material. The spintronics device 1 is provided with: an electrically conductive layer 2; an electrically conductive layer 3 with a carrier mobility or electric conductivity lower than that of the electrically conductive layer 2; and a boundary region 4 between the electrically conductive layers 2, 3. The boundary region 4 has a carrier mobility or electric conductivity gradient, and generates a spin current due to rotation of a velocity field of electrons caused by the gradient.
