A magnetic head including a first writer pole (100) disposed on a second writer pole (102). The second pole forms a magnetic path with the first pole and first pole includes a film with a chemical formula of (Fe60Co40)100-xMx. M can be one or more elements selected from the list of Hf, Zr, Ta, Nb, Cu, C, V, and Pd. The variable x can be in the range of approximately 9 to 14 atomic percent. The film can be of a thickness in the range of approximately 1 micron to 2 micron. The first pole and the second pole can be connected at one end. The film can include a sputtered thin film. The second pole can include the same film as the first pole. The film can include a very fine grain nanostructure phase. In another aspect of this invention, a method for forming a magnetic head is disclosed. The method includes depositing a first writer pole, and depositing a second writer pole adjacent to the first pole. The second pole forms a magnetic path with the first pole. The first pole includes a film as specified above. The first pole can be deposited at a pressure of approximately 5-25 mT.
