Abstract
The vacancies and vacancy clusters induced by the irradiation lead to the change of themagnetic structure around the defects. The reduction of the hyperfine magnetic field is caused by thelower superexchange field due to the formation of the O~(2-) vacancies. The change of direction of thehyperfine field has been also observed in Mossbauer spectra. On the other hand, the X-raydiffraction showed that the defects give rise to an increase of the lattice constant of the samples.
