Abstract

Official abstract text for this publication.

According to some aspects, a layered structure includes a memory layer, a magnetization-fixed layer, and a tunnel insulating layer. The memory layer has magnetization perpendicular to a film face in which a direction of the magnetization is configured to be changed according to information by applying a current in a lamination direction of the layered structure. The magnetization-fixed layer has magnetization parallel or antiparallel to the magnetization direction of the memory layer and comprises a laminated ferripinned structure including a plurality of ferromagnetic layers and one or more non-magnetic layers, and includes a layer comprising an antiferromagnetic material formed on a first ferromagnetic layer of the plurality of ferromagnetic layers and situated between the first ferromagnetic layer and the non-magnetic layer. The tunnel insulating layer is located between the memory layer and the magnetization-fixed layer.

First claim
