Title:
DOMAIN WALL MOTION ELEMENT, DOMAIN WALL MOTION TYPE MAGNETIC RECORDING ELEMENT AND MAGNETIC RECORDING ARRAY
Document Type and Number:
WIPO Patent Application WO/2020/095360
Kind Code:
A1
Abstract:
This domain wall motion type magnetic recording element (100) is provided with: a domain wall motion layer (10) in which first layers (11) that contain a rare earth metal and second layers (12) that contain a transition metal are alternately stacked in a first direction (Z); and a first electrode (21) and a second electrode (22), which face the domain wall motion layer, while being arranged at a distance from each other. The domain wall motion layer has SOT suppression parts (13) which are positioned in one of the interfaces between the first layers and the second layers, while containing a non-magnetic metal; and the SOT suppression parts are locally distributed at the interface.
