Abstract :
The influence on power loss PT of applied tensile stress σ in amorphous (Co0.89 Fe0.11 )72 Mo3 Si15 B10 ( 
) and Co73 Mo2 Si15 B10 ( 
) ribbons with different induced magnetic anisotropy Ku is reported. The losses are measured under sinusoidal flux conditions at 
Hz, 
T and at 
Hz, 
T. Measurements are carried out on samples in a stress-relieved state and with magnetic anisotropies induced by stress or field annealing. At Hz, a minimum m Pt versus σ is observed. The σ-value ( 
) corresponding to the minimum PT increases with increasing |Ku |. At Hz, a minimum in PT versus σ is observed in the samples with induced magnetic anisotropy, whereas 
in the stress-relieved samiales. However, no correlation between and and Ku is possible from the present data.
