Abstract
A topological spin memory effect, defined as the recovery of magnetic skyrmions or magnetic bubble skyrmions in magnetic thin films after a transition to a dramatically different spin texture, is used for encrypted non-volatile information storage. The storage strategy is based on magnetic skyrmions, that is, topologically protected spin textures comprising chiral domain walls surrounding small (e.g., nanometers to microns in diameter), typically circular, single-domain cores. Systems and methods are described for encrypted non-volatile information storage based on a spin memory effect in magnetic thin films that support skyrmions. Systems and methods encrypt and recover information stored in the form of magnetic skyrmions.
