Document Type and Number:
WIPO Patent Application WO/2023/149019
Kind Code:
A1
Abstract:
Provided is a magnetic storage device 10 comprising: a magnetoresistive element 11 having a structure in which a recording layer 13 that includes a first magnetic layer, a tunnel barrier layer 14, and a reference layer 15 that includes a second magnetic layer are laminated; and a control unit 12, wherein the in-plane shape of the recording layer 13 is such that a rectangle circumscribing the in-plane shape and having the smallest area has a short side and a long side which have mutually different lengths, and at the time of writing to the recording layer 13, the control unit 12 applies a voltage pulse to the magnetoresistive element 11 while applying an effective magnetic field in the direction of the short side in the plane of the recording layer 13.
