Systems, articles, and methods related to multilayered magnetic memory devices

A magnetic memory device comprising:

• a magnetic track extending in a first direction,
• wherein the magnetic track comprises:
• a lower magnetic layer;
• an upper magnetic layer on the lower magnetic layer;
• a non-magnetic pattern on the lower magnetic layer and at a side of the upper magnetic layer;
• and
• a spacer layer between the lower magnetic layer and the upper magnetic layer and extending between the lower magnetic layer and the non-magnetic pattern,
• wherein the lower magnetic layer and the upper magnetic layer are antiferromagnetically coupled to each other by the spacer layer,
• wherein the non-magnetic pattern has a first surface and a second surface, which are opposite to each other in a second direction perpendicular to the first direction, and the first direction and the second direction are parallel to a plane, and
• wherein a junction surface between the non-magnetic pattern and the upper magnetic layer is inclined with respect to a reference surface perpendicular to the first surface and the second surface of the non-magnetic pattern.
