Abstract
A method and system for providing a magnetic transducer is described. The method and system include providing an underlayer, a seed structure, and a magnetically hard layer. The underlayer has a surface. The seed structure resides on the surface and includes an amorphous layer and a seed layer. The amorphous layer wets the surface of the underlayer. The seed layer having a natural growth texture. The magnetically hard layer resides on the seed structure. The seed layer resides between the magnetically hard layer and the amorphous layer. The magnetically hard layer has a desired crystal orientation corresponding to the natural growth texture of the seed layer.
