Abstract
A magnetic head at high sensitivity and with enhanced output having a magnetoresistive element of high output and optimal for use in CPP-GMR, the magnetoresistive element comprising a pinned layer 606 containing a half-metal, a free layer 608 formed on one main surface of the pinned layer 606, a spacer 607 formed between the pinned layer 606 and the free layer 608, an anti-ferromagnetic layer 603 formed on the main surface of the pinned layer 606, a soft magnetic layer 604 formed between the pinned layer 606 and the anti-ferromagnetic layer 606, and a noble-metallic layer 605 formed between the pinned layer 606 and the soft magnetic layer.
