Magnetic and structural properties of Fe92−xNb7Cu1Bx alloys

Abstract The influence of B content on magnetic as well as structural properties of amorphous and nanocrystalline Fe 92− x Nb 7 Cu 1 B x ( x =8, 9, 12 at%) alloys was studied. Initial susceptibility χ measurements were done in order to investigate the influence of the nanocrystallization on soft magnetic properties of the given alloys. The temperature dependence of χ was measured up to 600°C for amorphous and nanocrystalline samples. The dependence of the initial susceptibility of the nanocrystalline samples on the B concentration shows magnetic softening. The crystallization effects were studied by means of the temperature dependence of the electrical resistivity.
