ABSTRACT:
A magnetoresistance device comprising at least two ferromagnetic layers separated by a non-magnetic layer, the coercive force of one of the ferromagnetic layers being enhanced by a coercive force enhancement layer of an antiferromagnetic material disposed adjacent to the one of the ferromagnetic layer thereby pinning magnetization inversion in the one of the ferromagnetic layer, the other ferromagnetic layer serving as a free ferromagnetic layer in which magnetization inversion is allowed, wherein the spin orientation in the coercive force enhancement layer is aligned in a multilayer fashion into a direction substantially parallel to the plane of the coercive force enhancement layer. A method of producing such a device is also disclosed.
