This study addresses the oxidation behavior of Fe38Co38Mo8B15Cu1 alloy. Amorphous, melt-spun ribbons were heat treated in an oxygen atmosphere for different times at 350 °C, 550 °C, and 800 °C. We focus on the change in structural, thermal, and magnetic properties induced by oxygen treatment. The low-temperature heat-treated samples displayed broad, continuous, and low-intensity X-ray diffraction peaks. While no structural change was observed in the heat treatments at 350 °C both 30 min and 480 min, a significant oxide formation was observed in the heat treatment at 800 °C for 480 min. DTA/TG analysis demonstrates the weight gains and oxide formation with the temperature and time of heat treatment increase. The weight gain occurs rapidly for the sample treated for 480 min at 800 °C. A remarkable change in magnetic properties was observed. Bulk oxidation is seen by Mössbauer analysis in the heat treatment of alloy in air at 800 °C. Besides hematite, a defective CoFe2O4 phase emerged aft...er 30 min, while after 480 min this phase was well-crystallized CoFe2O4.
