ABSTRACT:
A magnetoresistive film includes, arranged in the following order, a substrate, a first ferromagnetic layer, a non-magnetic metal film, and a second ferromagnetic layer which has a coercive force different from that of the first ferromagnetic layer. The magnetoresistive film has an uneven number of inflection point(s) in its magnetization hysteresis curve in the process of magnetization transition from a first saturation magnetization state to a second saturation magnetization state, with a magnetic field change quantity Hb and a magnetic field change quantity Ha being in the following relation:
