Abstract
A magnetic head for use in magnetic data storage systems is provided. The magnetic head includes a substantially non-magnetic writer gap layer and pair of magnetic poles separated by the writer gap layer. A first of the poles includes a first layer formed of a CoNiFe alloy that has a saturation magnetic moment greater than 2.1 Tesla. Methods of fabricating such a head are also disclosed.
