Abstract: Nanocomposites MgO-TM (TM = Ni3Fe, FeCo) were prepared by controlled heat treatment of compacted spark synthesised nanopowders. Main attention was paid to study of influence of interaction with surrounding atmosphere and adsorbed gases on phase composition and magnetic properties. Mössbauer 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.
