A spin valve sensor is provided with a spacer layer sandwiched between a free layer and a pinned layer. The pinned layer is pinned by a pinning layer constructed of a material having a high coercivity, and a low magnetic moment. The high coercivity is employed for pinning the pinned layer, and the low...http://www.google.fr/patents/US5867351?utm_source=gb-gplus-shareBrevet US5867351 - Spin valve read head with low moment, high coercivity pinning layer
