  • Method for changing spin relaxation, method for detecting spin current and spintronics device using spin relaxation
    Patent number: 8564293
    Abstract: The invention relates to a method for changing spin relaxation, a method for detecting a spin current, and a spintronic device using spin relaxation, and spin relaxation is changed through injection of a spin current. A spin current 4 is injected into a material 1 in a certain spin state, so that the spin relaxation time can be controlled.
    Type: Grant
