ABSTRACT:
A laminated ferrimagnetic thin film consists of two ferromagnetic layers and a non-magnetic intermediate layer sandwiched therebetween. The respective ferromagnetic layers are magnetically coupled in an anti-ferromagnetic manner through the non-magnetic intermediate layer. Each ferromagnetic layer consists of a plurality of layers. In each ferromagnetic layer, a layer which is in contact with the non-magnetic intermediate layer is formed of Co or an alloy including Co while at least one layer is formed of Ni or an alloy including Ni, and its film thickness is determined to be at least 60% or more of a film thickness of each ferromagnetic layer.
