A method for the batch fabrication of thin film magnetic heads with pole pieces having a preferred magnetic direction. The pole pieces are generated by growing, on a suitably oriented monocrystalline substrate, monocrystalline layers of zinc ferrite in zones corresponding to the respective geometrical form of the pole pieces, these layers having an inserted component (e.g. Ni) which renders the ferrite ferromagnetic. The Ni component may be added during the growing process or afterwards inserted in, or removed from homogeneous layers by a masked diffusion process.
