Effects of Energetic Heavy Ion Irradiation on the Structure and Magnetic Properties of FeRh Thin Films

Résumé

Fe-54at.%Rh thin films were irradiated with 10MeV iodine ions at room temperature. Before and after the irradiations, the changes in magnetic properties and the lattice structure of the samples were studied by means of a SQUID magnetometer and X-ray diffraction. For the low fluence irradiation, the SQUID measurement at 20K shows that the anti-ferromagnetic region of the thin film is changed into ferromagnetic region by the irradiation. For the high fluence irradiation, the magnetization of the film is strongly decreased by the irradiation, which can be explained as due to the change in lattice structure from B2 into A1 structure by the irradiation.
