SPIN ORBITAL TORQUE-TYPE MAGNETIZATION ROTATION ELEMENT, SPIN ORBITAL TORQUE-TYPE MAGNETO-RESISTIVE EFFECT ELEMENT, AND MAGNETIC MEMORY

摘要

This spin orbital torque-type magnetization rotation element (10) is provided with: a spin orbital torque wiring (2) that extends in a first direction (x); a first ferromagnetic layer (1) that is laminated in a second direction (z) intersecting the spin orbital torque wiring; and a first nonmagnetic metal layer (3) and a second nonmagnetic metal layer (4) that are connected to the spin orbital torque wiring at positions flanking the first ferromagnetic layer in the first direction in a plan view from the second direction, wherein the gravity center (G) of the first ferromagnetic layer is positioned on a side closer to the first nonmagnetic metal layer or the second nonmagnetic metal layer than is a reference point (S) located at the center between the first and second nonmagnetic metal layers in the first direction.
