Spintronics memory cell and method of manufacturing the same, memory, and method of storing information

Abstract

The memory cell includes: a piezoelectric substrate layer, wherein two ends of the piezoelectric substrate layer are respectively provided with a first electrode and a second electrode, and a current-free drive of skyrmion is implemented by applying a voltage to the first electrode and the second electrode; a magnetic layer on a surface of the piezoelectric substrate layer, wherein the magnetic layer is used to form a heterojunction with the piezoelectric substrate layer, and is used to generate, stabilize, and serve as a basic carrier for a movement of the skyrmion; wherein the magnetic layer includes a convex body, the convex body is configured to divide the magnetic layer into a bit region and a memory region, and the bit region is provided with a magnetic tunnel junction used to perform generation and detection functions of the skyrmion.
