Magnetic and structural properties of Fe92-xNb7Cu1Bx alloys

The influence of B content on magnetic as well as structural properties of amorphous and nanocrystalline Fe92-xNb7Cu1Bx (x = 8, 9, 12 at%) alloys was studied. Initial susceptibility chi measurements were done in order to inve stigate the influence of the nanocrystallization on soft magnetic propertie s of the given alloys. The temperature dependence of chi was measured up to 600 degrees C for amorphous and nanocrystalline samples. The dependence of the initial susceptibility of the nanocrystalline samples on the B concent ration shows magnetic softening. The crystallization effects were studied b y means of the temperature dependence of the electrical resistivity. (C) 20 00 Elsevier Science B.V. All rights reserved.
