Abstract

A member having a first and a second magnetic layer are magnetostatically coupled and laminated and the first magnetic layer formed on a magneto-resistive element, for creating the exchange coupling on the magneto-resistive element and the first magnetic layer. The member is formed by sequentially laminating a first ferromagnetic layer magnetized in a sense along the direction of the longitudinal bias of the magneto-resistive element, non-magnetic layer and second ferromagnetic layer magnetized in a direction opposite to the magnetized direction of the first ferromagnetic layer, for example.
