Resumo

Measurements of the magnetic resonance spectra of BaxSr2-xFeCoO6 ceramics (x = 0, 0.1, 0.3, 0.5) were carried out in a wide temperature range from 300 to 700 K. At temperatures above 466, 519 and 472 K, phase transitions were observed for samples BaxSr2-xFeCoO6 x = 0.1, 0.3 and 0.5, respectively. The activation energy of the small polaron responsible for the jump conductivity was determined.
