Abstract
The effect of a constant axial magnetic field on the temperature dependences of the high-frequency electrical impedance of amorphous cylindrical wires of Co66Fe4Nb2.5Si12.5B15 is studied and discussed. In the region of the ferromagnetic phase transition, the action of an axial magnetic field leads to a significant change in the temperature dependence of the impedance measured at frequencies below 10 MHz. The revealed features are explained by the presence of two magnetic phases with different Curie temperatures and different distributions in the bulk of the wire.
