Abstract

The amorphous state of ferromagnetic Fe₇₈Si₉B₁₃ (Metglas 2605S-2) and its nanocrystallization were investigated by in situ transmission electron microscope (TEM), X-ray diffraction (XRD), Moessbauer spectroscopy (MS), differential scanning calorimeters (DSC) and magnetic moment measurements. The Moessbauer spectrum exhibited an essentially symmetric hyperfine field pattern of 259 KOe in as-quenched amorphous state at room temperature. The Curie and crystallization temperature were determined to be T_C = 708 K and T_x = 803 K, respectively. The T_x value was in good agreement with DSC measurement results. The occupied fraction of the nanocrystalline phases of α-Fe(Si) and Fe₂B at in situ optimum annealing temperature was about 57% and 43%, respectively. It is notable that the magnetization of the amorphous phase decreases more rapidly with increasing temperature than those of nanocrystalline ferromagnetism, suggesting the presence of the distribution of exchange interaction in the amorphous phase or high metalloid contents.
