Abstract
Provided are a magnetic film, a magnetoresistance effect element and a magnetic memory which take advantages of atop-pinned structure and a bottom-pinned structure, maintain perpendicular magnetic anisotropy of magnetic layers in a fixing layer and allow strong pinning even in an annealing treatment after a protective film is formed. A fixing layer of a magnetic film has a basic configuration in which a first magnetic layer (), a first non-magnetic layer (), a first Pt layer (), a second magnetic layer () disposed adjacent to each other in this order. The magnetization directions of the first magnetic layer () and the second magnetic layer () are both a direction perpendicular to the film surface, and an antiferromagnetic coupling is formed between the first magnetic layer () and the second magnetic layer ().
