Tensile stress dependence of the coercivity and magnetostriction of stress-annealed (by Joule heating) Co66Fe4Mo2Si16B12 alloy

Abstract The influence of applied tensile stresses (16–45 MPa) during Joule-heating thermal treatments on samples of nominal composition Co 66 Fe 4 Mo 2 Si 16 B 12 is reported. The influence of high axial stresses (0–1000 MPa, applied during measurements) on the coercive field was also investigated. The coercive field exhibited a maximum as a function of measuring stress. Very low values of the saturation magnetostriction constant have been obtained as a function of annealing stress.
