Document Type and Number:
WIPO Patent Application WO/2020/230771
Kind Code:
A1
Abstract:
A magnetic domain wall moving element of the present embodiment comprises: a magnetic recording layer that extends in a first direction and includes a ferromagnetic body; and a first electrically conductive layer and a second electrically conductive layer each connected to the magnetic recording layer and spaced apart from each other. The first electrically conductive layer has a ferromagnetic first layer that contacts the magnetic recording layer. The first layer has a mixing layer at the interface with the magnetic recording layer, and the mixing layer is a mixture of the ferromagnetic body and a dissimilar metal. The dissimilar metal is a metal that is different from the ferromagnetic body that mainly constitutes the first layer, and from the ferromagnetic body that mainly constitutes the magnetic recording layer.
