Abstract

Magnetic resonance spectra of BaxSr2 – xFeCoO6 ceramics (x = 0, 0.1, 0.3, 0.5) were measured over a wide temperature range from 300 to 700 K. At temperatures above 466, 519, and 472 K for samples with x = 0.1, 0.3, and 0.5, in BaxSr2 – xFeCoO6, phase transition from paramagnetic to ferromagnetic ordering was observed. The activation energy of the small polaron responsible for hopping conduction was determined.
