  • Abstract
    The influence on power loss PTof applied tensile stress σ in amorphous (Co0.89Fe0.11)72Mo3Si15B10( \\lambda _{s} > 0 ) and Co73Mo2Si15B10( \\lambda _{s} < 0 ) ribbons with different induced magnetic anisotropy Kuis reported. The losses are measured under sinusoidal flux conditions at f = 50 Hz, J_{\\max } = 0.57 T and at f = 400 Hz, J_{\\max } = 0.10 T. Measurements are carried out on samples in a stress-relieved state and with magnetic anisotropies induced by stress or field annealing. At f = 50 Hz, a minimum m Ptversus σ is observed. The σ-value ( \\sigma _{\\min} ) corresponding to the minimum PTincreases with increasing |Ku|. At f = 400 Hz, a minimum in PTversus σ is observed in the samples with induced magnetic anisotropy, whereas \\sigma _{\\min} = 0 in the stress-relieved samiales. However, no correlation between and \\sigma _{\\min} and Kuis possible from the present data.
