Title:
MAGNETORESISTIVE ELEMENT AND MAGNETIC MEMORY
Document Type and Number:
WIPO Patent Application WO/2019/187800
Kind Code:
A1
Abstract:
Provided are a magnetoresistive element which has magnetic shape anisotropy and uses a recording layer having antiparallel coupling, and a magnetic memory. Said magnetoresistive element has a structure in which: a first magnetic layer (3) and a second magnetic layer (5) include a ferromagnetic material and are magnetically coupled in an antiparallel direction, and the magnetization direction can change to the direction perpendicular to the film surface; and a junction size D (nm) which is the length of the longest straight line on an end surface perpendicular to the thickness direction of the first magnetic layer (3) and the second magnetic layer (5), a film thickness t1 (nm) of the first magnetic layer (3), and a film thickness t2 (nm) of the second magnetic layer (5) have between them a relationship D < t1 and D ≤ t2, or a relationship D ≤ t1 and D < t2.
