Abstract
In one general embodiment, a method includes performing a reducing operation for reducing a native oxide along a surface of a CoFe layer of a magnetic transducer, after performing the reducing operation, performing an oxidation operation for oxidizing the surface of the CoFe layer, and after performing the oxidation operation, forming a layer of at least partially crystalline alumina on the oxidized surface of the CoFe layer.
