Spin valve magnetoresistive head and method of manufacturing the same and magnetic memory apparatus

摘要

A spin valve magnetoresistive head comprises a first spin valve device (3) having a first magnetization free layer (3c) and a first magnetization pinning layer (3a) via a first non-magnetic intermediate layer (3b), a second spin valve device (4) having a second magnetization free layer (4c) and a second magnetization pinning layer (4a) via a second non-magnetic intermediate layer (4b), whereby the first and second magnetization pinning layers (3a,4a) are magnetized in anti-parallel to each other and the first and second magnetization free layers (3c,4c) are magnetized rotatably based on an external magnetic field.
