磁记忆及其制造方法

Magnetic memory and manufacturing method thereof
Abstract:
A magnetic memory has a magnetic recording layer, a reference layer connected via a non-magnetic layer to the magnetic recording layer, first and second magnetization pinning layers disposed below the magnetic recording layer. The magnetic recording layer and the reference layer have a perpendicular magnetic anisotropy. The magnetic recording layer has a magnetization reversal region having a reversible magnetization and overlapping the difference layer, a first magnetization pinned region connected to a first boundary of the magnetization reversal region with the direction of the magnetization being fixed in a first direction, and a second magnetization pinned region connected to a second boundary of the magnetization reversal region with the direction of magnetization being fixed in a second direction anti-parallel to the first direction. The first and the second magnetization pinning layers fix the magnetization of the first and the second magnetization pinned regions.
