Title:
SPIN-CURRENT ASSIST TYPE MAGNETORESISTANCE EFFECT DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/208880
Kind Code:
A1
Abstract:
A spin-current assist type magnetoresistance effect device (200) according to the invention of the present application is provided with: a spin-current assist type magnetoresistance effect element (100) including a magnetoresistance effect element part (20) and a spin orbit torque wiring (40); and a control unit (110) electrically connected to the spin-current assist type magnetoresistance effect element, wherein an STT inversion current (I1) flowing through the magnetoresistance effect element part and an SOT inversion current (I2) flowing through the spin orbit torque wiring are joined together or branched from each other at a portion where the magnetoresistance effect element part and the spin orbit torque wiring are bonded to each other, and the control unit can perform control such that the STT inversion current is applied to the spin-current assist type magnetoresistance effect element at a timing the same as that of the SOT inversion current or at a timing later than that of the SOT inversion current.
