| Outline of Final Research Achievements |
Iron-rhodium ordered alloy has a first-order phase transition from the lowtemperature antiferromagnetic (AF) phase to the high-temperature ferromagnetic (FM) phase near room temperature. We have reported that the ion beam irradiation at various energies can induce the FM state in FeRh bulk and film samples below room temperature at which they are originally in the AF state.
We have succeedded to fabricate micro scale magnetic patterns using the ion microbeam technique, hereby novel applications such as for patterned media may be feasible. We also realized that ferromagnetic layered structure has been made at sub-surface of the antiferromagnetic FeRh bulk samples by high energy He ion beam irradiation. The possibility of two and three dimensional magnetic patterning for the FeRh thin films and bulks by high and low energy ion beam as well as by cluster ion beam irradiation has been shown.
