Abstract :
The effective magnetic anisotropy and saturation magnetostriction of both amorphous and nanocrystalline (samples with different microstructures) Fe83Zr7B8Cu2 alloy have been investigated. The effective anisotropy results were obtained through the measurement of the bias field dependence of the transverse susceptibility in samples annealed from 480 to 600°C. In the above mentioned range, the annealing temperature dependence of the saturation magnetostriction is related to the presence of a nanocrystalline structure leading to a remarkable magnetic softening. From our results it was possible to discern the occurrence of intergranular coupling and to evaluate the typical dimensions of the coupled units
