Main attention was paid to study of influence of interaction with surrounding atmosphere and adsorbed gases on phase composition and magnetic properties. M\u00F6ssbauer spectroscopy, x-ray diffraction and TEM were used for phase analysis. Changes in structure and phase composition during annealing were detected using thermomagnetic curves and DTA/TG measure-ments and completed with gas analysis using mass spectroscopy." . . . "322" .
