Abstract:

A GMR stack has at least two ferromagnetic layers e.g., CoFe spaced from each other by a nonferromagnetic layer e.g., Cu. A layer of a phase-breaking material such as Ta or a Ta-base alloy between, the nonferromagnetic layer and at least one of the two ferromagnetic layers prevents the undesirable growth of large-grained structures in the ferromagnetic layers
