IRRADIATION EFFECT OF 0.56 GeV C 6+ on Y 1.6 Ca 1.4 V 0.45 Sn 0.5 Fe 4.05 O 12 1 corresp first-author Present address: Analytical and Testing Center, Southeast University, Nanjing 210018, China Present address: Analytical and Testing Center, Southeast University, Nanjing 210018, China 1 2 Physics Department of Nanjing University, Nanjing 210008, China Physics Department of Nanjing University, Nanjing 210008, China Institute of Modern Physics, the Chinese Academy of Sciences, Lanzhou 730000, China Institute of Modern Physics, the Chinese Academy of Sciences, Lanzhou 730000, China Y 1.6 Ca 1.4 V 0.45 Sn 0.5 Fe 4.05 O 12 is irradiated by 0.56 GeV carbon ion. The irradiation effect is investigated by Mössbauer spectroscopy. The irradiation results in an isotropic distribution of the hyperfine magnetic field. The hyperfine magnetic fields decrease after the irradiation due to the change of supertransferred field. After the irradiation, the chain Fe(a)-oxygen-Fe(d) become longer and it leads to decrease of the supertransferred field.
