The magnetoimpedance of Fe76.5-xCrxSi13.5B9Nb3Au1 ( x = 1, 2, 3, 4, 5) alloys has been
measured to investigate the influence of crystallization process on the soft magnetic properties and magnetic
anisotropy after thermal treatment. Annealing performed at 540 and 550 ?C for 30 min in a vacuum
indicated that ultrasoft magnetic properties of nanocomposite materials are obtained. The
magnetoimpedance ratio (MIR) and incremental permeability ratio (PR) measurements show that the
maximum values of MIR and PR increase drastically in the heat-treated samples. It means that the samples
are softened by nanocrystallization. The PR curves become narrower and sharper due to the decrease of
anisotropy. The MIR behavior related with the softness of magnetic properties of heat-treated samples and
the incremental PR strongly changes with external magnetic field. ?? 2006 Elsevier B.V. All rights reserved. |
