The Barkhausen effect in Fe–V alloys

Soft magnetic alloys with amorphous and ultra-fine grain structure upon loading with hydrogen

“…Obviously, the electronic and then the magnetic properties might be modified as well as the mechanical ones. As a matter of fact, to support this assumption is the very strong influence of hydrogenation on the Barkhausen effect generally exhibited by amorphous and crystalline alloys [4][5][6]. In this work, we report on the structural and magnetic properties measured before and after hydrogenation in amorphous Fe-rich ribbons.…”

Hydrogen effect on the sigma-phase in Fe53.8Cr46.2

“…Accordingly, the cathodic current density was fixed to 250 A/m 2 . Measurements of microhardness by a standard method, X-ray diffraction analyzes using a PW mator) and Barkhausen effect measurements according to a method described in [6], were undertaken immediately after achieving hydrogenation and 6 months later. The Mössbauer spectroscopy measurements were performed at room temperature 2 days after the hydrogenation, as well as at 10 and 4.2 K, 1 month after loading with hydrogen.…”
