Y1.6Ca1.4V0.45Sn0.5Fe4.05O12 has been bombarded with a 0.56 GeV C6+ ion beam. The vacancies and vacancy clusters induced by the irradiation change the directions of hyperfine fields around the defects. The reduction of the magnetic hyperfine field is caused by the lower superexchnage field due to the formation of the O2− vacancies. The change of direction of the hyperfine field has also been observed in Mössbauer spectra. X-ray diffraction showed that the defects give rise to an increase of the lattice constant of the samples.
