摘要

Experimental data onuniaxial in-plane anisotropy field (H_K) and magnetostriction (λ_s) of the amorphous and nanocrystalline Fe_(71.5)Cu_1Nb_3 Al_2Si_(13.5)B_9 alloy obtained by ferromagnetic resonance (FMR) method are presented. The results are compared with those obtained by the transverse biased initial susceptibility method. The nanostructured phase was produced by means of thermal treatment (480-600℃ during 1 h) to develop the devitrification of the precursor amorphous material. The role of the Al enhancing the soft magnetic character with respect to the Al-free classical Finemet composition are also analyzed.
