Abstract
Provided is a magnetoresistance effect element in which the magnetization direction of the recording layer is perpendicular to the film surface and which has a high thermal stability factor Δ, and a magnetic memory. A recording layer having a configuration of first magnetic layer/first non-magnetic coupling layer/first magnetic insertion layer/second non-magnetic coupling layer/second magnetic layer is sandwiched between the first and second non-magnetic layers and stacked so that a magnetic coupling force is generated between the first magnetic layer and the second magnetic layer.
