Abstract:
1. A method for manufacturing a magnetoresistive multilayer film, comprising: laminating an antiferromagnetic layer, a pinned-magnetization layer, a nonmagnetic spacer layer and a free-magnetization layer in this order on a substrate; depositing a film for the antiferromagnetic layer by a sputtering process as oxygen gas is added to a gas for sputtering; and depositing films for the pinned-magnetization layer, the nonmagnetic spacer layer and the free-magnetization layer by sputtering processes as oxygen gas is not added to a gas for sputtering, wherein the film for the antiferromagnetic layer is made of PtMn alloy or IrMn alloy.
