ABSTRACT:
There have been known various methods for controlling the magnetic anisotropy of a magnetic film with a magnetic field being applied thereto. In accordance with the present invention, the magnetic anisotropy is controlled by implanting ions into the magnetic film while applying a magnetic field thereto. The direction for applying the magnetic field can be arbitrarily selected, for example, along an inplane direction of the magnetic film and along a direction vertical thereto. The magnetic anisotropy can be controlled only in the desired areas by limiting the areas to which ions are implanted with a mask disposed on the magnetic film.
