A magnetic head in a magnetic storage system is provided in which materials that do not individually display high permeability and low coercivity are satisfactorily employed in a write head when coupled to adjacent high permeability layers. The magnetic head includes a gap layer which separates a pair of poles. At least one pole of the pair of poles includes a pole layer formed of a high permeability material and a seed layer adjacent to the pole layer. The seed layer is formed of a high moment low permeability material having a high saturation magnetic moment greater than 2.1 Tesla and a low permeability of about 10-100. The high permeability material of the pole layer causes the permeability of the adjacent seed layer to substantially increase from about 10-100 to about 1400-1600, thereby providing a pole with high permeability and high saturation moment. In addition, a method of forming a magnetic head for use in a magnetic storage system is provided.
