摘要： Magnetic films having magnetic regions and non-magnetic regions are disclosed. The film is subjected to ion irradiation in order to produce chemically disordered regions in the film. The irradiated disordered regions may correspond to the non-magnetic regions of the film. Alternatively, the irradiated disordered regions may correspond to the magnetic regions of the film. In one embodiment, portions of a magnetic CrPt3 film are converted to non-magnetic regions by irradiating the regions with boron ions which disorder the CrPt3 film in the treated regions. The film may be patterned into magnetic regions and non-magnetic regions for applications such as magnetic recording media in computer disc drive systems.
