Abstract
A process resulting in enhanced pole performance, relative to permalloy poles, in narrow track magnetic devices. A preferred process includes increasing the anisotropy field of the pole material while maintaining an acceptable coercivity level and near zero magnetostriction. One embodiment utilizes a NiCoFe alloy containing 22% cobalt by weight, heat treated in an easy axis magnetic field in a non-oxidizing atmosphere. This process achieves favorable domain structures at narrow pole tip widths.
