Abstract
Comprehensive studies of powders with a nominal composition of 90% [43% Fe2O3–57% FeO]–10% Gd2O3 are performed via scanning electron microscopy, microscopic X-ray spectral and phase analysis, differential scanning calorimetry, and measuring hysteresis properties. It is shown that the main phases in the powders after high-energy ball milling are magnetite (Fe3O4) and an amorphous phase; in addition, the powders contain about 2 vol % wustite (FeO) and less than 1 vol % orthoferrite (GdFeO3). Trends of changes in the phase composition, structure, and hysteresis properties of the annealed powders are identified.
