Abstract

A magnetic domain wall movement type magnetic recording element includes: a first ferromagnetic layer which includes a ferromagnetic body; a non-magnetic layer which faces the first ferromagnetic layer; and a magnetic recording layer which faces a surface of the non-magnetic layer on a side opposite to the first ferromagnetic layer and extends in a first direction. The magnetic recording layer has a concave-convex structure on a second surface opposite to a first surface which faces the non-magnetic layer.
