By fitting theoretically calculated to experimentally found lg UT f 1/T dependencies ( u conductivity) there were obtained : the free formation enthalpy of anti-Frenkel defects gAB = 1.81 eV -7.85 kT, and the mobilities v, and V I of Fion vacancies and interstzials: v,T = 240 exp (-0.59 eV/kT) cm2 K
