Popis:	The bias magnetic field ( H ) dependence of the longitudinal sound velocity ( v ) in Fe 77.5 Si 7.5 B 15 glass covered amorphous wires is reported. The amorphous wires were tested in the as-cast state and after dc current annealing between 5 and 20 mA for 10–30 min. For the glass covered amorphous wires tested in the as-cast state the bias magnetic field dependence of the sound velocity was insignificant. For current annealed samples a decrease of the sound velocity for the smaller bias magnetic fields was observed. Increasing the annealing temperature, the bias magnetic field corresponding to the v minimum decreased. For about 600 A/m bias magnetic field, the longitudinal sound velocity reaches saturation.
