Abstract
The present invention makes it possible to inhibit an MR ratio from decreasing by high-temperature heat treatment in a magnetoresistive effect element using a perpendicular magnetization film. The magnetoresistive effect element includes a data storage layer, a data reference layer, and an MgO film interposed between the data storage layer and the data reference layer. The data storage layer includes a CoFeB film coming into contact with the MgO film, a perpendicular magnetization film, and a Ta film interposed between the CoFeB film and the perpendicular magnetization film. The CoFeB film is magnetically coupled to the perpendicular magnetization film through the Ta film.
