摘要: Temperature dependent Mossbauer and ferromagnetic resonance (FMR) measurements have been performed with thermal decomposition products of NaX.Fe(CO) 5 after various steps heat treatment, in vacuum or under gas atmosphere (argon, H 2 ). The measured spectra consistently were analyzed using superparamagnetic relaxation behavior magnetic particles. From this analysis information concerning composition size iron particles is derived, questions their catalytic properties are briefly discussed.
