Magnetoelastic acoustic emission in ferrosilicon single crystals

The influence of magnetic-reversal effects on magnetoelastic acoustic emission (MAE) in single crystals of Fe + 3% Si cut in the [100], [110], and [111] directions is investigated, along with the relationship of these signals to the linear magnetostriction. It is shown that the MAE signals depend on the crystallographic directions and exhibit processes associated with rearrangement of the 90° domains throughout the entire volume of the ferromagnet.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 1, pp. 62–66, January, 1986.
