Outline of Final Research Achievements

In this study, we examine the possibility of the spin current confinement and enhancement by using the nano constricted structure where magnetization rapidly changes in order to utilize the spin current for applications. The spin current created by the heat current was increased as decreasing the areal density of the nano constricted region. It suggests that the rapid magnetization change has the possibility to confine and enhance the spin current.
