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 layer606containing a half-metal, a free layer608formed on one main surface of the pinned layer606, a spacer607formed between the pinned layer606and the free layer608, an anti-ferromagnetic layer603formed on the main surface of the pinned layer606, a soft magnetic layer604formed between the pinned layer606and the anti-ferromagnetic layer606, and a noble-metallic layer605formed between the pinned layer606and the soft magnetic layer.
