Magnetic Properties and Glass-Forming Ability of CoFeSiBNb Alloys

Abstract

The effect of small tin, gallium, and zirconium additions on the magnetic properties of a Co₄₈Fe₂₅B₁₉Si₄Nb₄ alloy at high temperatures is studied. The temperature dependences of the magnetic susceptibility of the compositions under study are measured; the electron characteristics, such as the effective magnetic moment, the density of electron states at the Fermi level, and the paramagnetic Curie temperature, are calculated. Amorphous alloy samples are prepared by melt injection and vacuum suction casting.
