Title:
SPIN-ORBIT TORQUE MAGNETIZATION ROTATION ELEMENT, SPIN-ORBIT TORQUE MAGNETORESISTANCE EFFECT ELEMENT, MAGNETIC MEMORY, AND HIGH-FREQUENCY MAGNETIC ELEMENT
Document Type and Number:
WIPO Patent Application WO/2020/110296
Kind Code:
A1
Abstract:
This spin-orbit torque magnetization rotation element is provided with: a first ferromagnetic layer; a spin-orbit torque wire having a first surface facing the first ferromagnetic layer and a major axis extending in a first direction in a plan view seen from the layering direction of the first ferromagnetic layer; and an underlayer which contacts a second surface of the spin-orbit torque wire opposite the first surface thereof. The spin-orbit torque wire has, at positions overlapping the first ferromagnetic layer in the plan view seen from the layering direction, a first domain having a first crystal orientation axis and another region having a different crystal state from the first domain. The first crystal orientation axis of the first domain is continuous from the underlayer.
