Abstract:
The effect of interaction of the surface of ribbons of amorphous soft-magnetic alloys with water on the magnetization distribution and magnetic properties has been investigated on the example of ribbons of amorphous rapidly quenched alloys Fe(81)B(13)Si(4)C(2) and Fe(77)Ni(1)Si(9)B(13). It has been shown by these investigations that the interaction of the surface of ribbons of amorphous silicon-containing soft-magnetic iron-based alloys with water leads to a reduction in the maximum magnetic permeability. The decrease in mu(max) is caused by a magnetization redistribution in the plane of the ribbon, namely, by an increase in the volume of domains with an in-plane magnetization oriented transversely to its axis. This is connected with the formation in this direction, due to a locally directed ordering, of an enhanced concentration of atoms incorporated into the ribbon surface and inducing a pseudo-uniaxial tension that favors a reorientation of the magnetization. The degree of changes in the magnetic properties depends on the temperature of water.
