The uniaxial magnetic anisotropy induced by magnetic annealing was studied for rapidly quenched amorphous Fe100-xBx (12≤x≤25) and Co100-xBx (17≤x≤30) alloys. The value of induced uniaxial anisotropy constant Kui increased with increasing B content from 1 x 103 erg/cm3 at x = 12 to about 4 x 103 erg/cm3 at x = 25 in Fe100-xBx alloy s exhibiting an inflection around x=20. While the value of Kui in Co100-xBx alloys exhibits a maximum of about 6 x 103 erg/cm3 aro round x=20. The compositional dependence of Kui for both alloy systems can be explained roughly by the model of the directiona; occupation of B atom between ferromagnetic atoms.
