Abstract :
In this work the influence of nanocrystalline structure on magnetic losses is pointed out. Annealed samples, with and without SiO 2 coating, show mainly hysteretic losses. Eddy current losses are more important in the as cast state than in the other cases. These measurements suggest that the occurrence of the nanocrystalline structure modifies the wall kinetics and so the contribution of eddy current losses in comparison with the amorphous state
