ABSTRACT:
A magnetic head is provided with a giant magnetoresistive element, barrier layer, and highly polarized spin injection layer, The barrier layer is inserted between the giant magnetoresistive element and the injection layer. By applying a sensing current to both the magnetoresistive element and the injection layer, an output of the magnetic head can be multiplied significnantly. The output of the head is increased by increasing a resistance change rate of a magnetoresistive element used as a reading element. The increasing of the resistane change rate is due to that a band of s electrons in the Cu film grown in the highly polarized spin injection layer is placed in a highly polarized state near the Fermi level and the upward spin current only flows into the giant magnetoresistive element, which has multiplied the output.
