1. A magnetic read head including a magnetoresistive sensor where sense current flows in a stacking direction of the magnetoresistive sensor, the magnetoresistive sensor comprising:

  • a free layer having a magnetization direction that is affected by external magnetic fields and including a Heusler alloy layer and a Co-based amorphous metal layer;

    a fixed layer which is stacked with the free layer and has a fixed magnetization direction; and

    a non-magnetic intermediate layer between the free layer and the fixed layer.
