Abstract
A domain wall moving type magnetic recording element includes: a domain wall moving layer in which first layers containing a rare earth metal and second layers containing a transition metal are alternately stacked in a first direction; and a first electrode and a second electrode which face the domain wall moving layer and are arranged to be away from each other. The domain wall moving layer has SOT suppression parts which are positioned in one of interfaces between the first layers and the second layers and contain a non-magnetic metal. The SOT suppression parts are locally distributed at the interface.

A domain wall moving element, comprising:
- a domain wall moving layer in which first layers containing a rare earth metal and second layers containing a transition metal are alternately stacked in a first direction;
- and
- a first electrode and a second electrode which face the domain wall moving layer and are arranged to be away from each other,
- wherein the domain wall moving layer has spin-orbit torque (SOT) suppression parts which are positioned in one of interfaces between the first layers and the second layers and contain a non-magnetic metal, and
- the SOT suppression parts are locally distributed at the interface.
