Abstract :
The chill-cast alloy, Fe75Si15B10, consists of submicron rods of Fe2B, a magnetically "hard\´ phase with high Tc, in a matrix of Fe3Si, a "soft" phase with low Tc. Magnetic properties change markedly on cooling through 590°C, the Tcof Fe3Si, and 245°C, where the magnetocrystalline anisotropy of Fe2B changes from easy-axis to easy-plane. The unusual magnetic and thermomagnetic behavior observed is discussed in terms of the short-range and long-range magnetostatic interactions between the two phases.
