Title:
MAGNETIC FILM, MAGNETORESISTIVE ELEMENT, AND MAGNETIC MEMORY
Document Type and Number:
Japanese Patent JP2022033026
Kind Code:
A
Abstract:
To provide a magnetic film, a magnetoresistive element, and a magnetic memory that maintain the vertical magnetic anisotropy of a magnetic layer in a fixed layer and enables strong pinning even by annealing after a protective film is formed, while taking advantage of a top pin structure and a bottom pin structure.SOLUTION: A fixed layer of a magnetic film has a basic configuration in which a first magnetic layer 21, a first non-magnetic layer 31, a first Pt layer 41, and a second magnetic layer 22 are arranged adjacent to each other in this order. The magnetization directions of the first magnetic layer 21 and the second magnetic layer 22 are both perpendicular to the film surface, and an antiferromagnetic bond is formed between the first magnetic layer 21 and the second magnetic layer 22.SELECTED DRAWING: Figure 22
