ELECTRIC-CURRENT-GENERATED MAGNETIC FIELD ASSIST TYPE SPIN-CURRENT-INDUCED MAGNETIZATION REVERSAL ELEMENT, MAGNETORESISTANCE EFFECT ELEMENT, MAGNETIC MEMORY AND HIGH-FREQUENCY FILTER

摘要

The present invention has the purpose of providing an electric-current-generated magnetic field assist type spin-current-induced magnetization reversal element that utilizes magnetization reversal based on pure spin current. The electric-current-generated magnetic field assist type spin-current-induced magnetization reversal element of the present invention includes a first ferromagnetic metal layer with a varying magnetization direction; spin-orbit torque wiring that adjoins the first ferromagnetic metal layer and that extends in a second direction in a plane orthogonal to a first direction normal to the first ferromagnetic metal layer; and electric-current-generated magnetic field assist wiring that is arranged so as to be electrically insulated from the first ferromagnetic metal layer by an insulating layer and in which flows an electric current I₀ for forming a magnetic field H₀ that assists magnetization reversal of the first ferromagnetic metal layer.
