Abstract
A study of the magnetic anisotropy originated by the nanocrystallization of the amorphous Co 66 Si 16 B 12 Fe 4 Mo 2 is presented. Mechanically polished samples of this alloy were submitted to various thermal treatments to obtain different degrees of crystallization. The results show that an homogeneous distribution of nanocrystallites of about 10 nm originates a magnetic anisotropy of 18 J m - 3 while the larger crystals that appear, due to the coalescence of the small crystallites, with annealings over 500 ∘ C produce an increase of the magnetic anisotropy up to values of about 100 J m - 3 , that are similar to the ones of the as-quenched material. From the value of the effective magnetic anisotropy constant we deduce that in the samples annealed below the onset temperature, the majority of the crystallites are of Co 2 B and Co 3 B .
