Title:
MAGNETIC STORAGE ELEMENT, MAGNETIC HEAD, MAGNETIC STORAGE DEVICE, ELECTRONIC DEVICE, AND METHOD FOR PRODUCING MAGNETIC STORAGE ELEMENT
Document Type and Number:
WIPO Patent Application WO/2019/244662
Kind Code:
A1
Abstract:
The present invention provides a magnetic storage element that has a multilayer structure which is composed of a fixed layer (102) that has a fixed magnetization direction, a storage layer (106) that has a reversible magnetization direction, and a non-magnetic layer (104) that is held between the fixed layer (102) and the storage layer (106). With respect to this magnetic storage element, the magnetization direction is along the stacking direction of the multilayer structure; and the fixed layer (102) or the storage layer (106) has a region which contains at least one content element that is selected from the element group consisting of B, C, N, Al, Mg and Si in an amount of from 30 atom% to 80 atom% (inclusive).
