Abstract

A thermally assisted magnetic writing device including a first magnetic layer known as the “reference layer,” a second magnetic layer known as the “storage layer” that presents a variable magnetization direction, a spacer situated between the reference layer and the storage layer and a first antiferromagnetic layer in contact with the storage layer, the first antiferromagnetic layer being able to trap the magnetization direction of the storage layer. The magnetic device also includes a stabilization layer made of a ferromagnetic material, the stabilization layer being in contact with the first antiferromagnetic layer.
