Magnetoresistance effect element

摘要

There is provided a magnetoresistance effect element comprising a substrate (4) and at least two magnetic thin layers (1, 2) which are laminated with interposing a non-magnetic thin layer (6) therebetween on said substrate (4) wherein adjacent magnetic thin layers (1, 2) through the non-magnetic thin layer have different coercive forces, characterized in that a metal thin film (3) is provided in an interface between at least one of the magnetic layers (1, 2) and the non-magnetic layer (6) which is adjacent thereto and the metal thin film (3) is made of a substance which is different from that of the adjacent non-magnetic layer (6).
