Zusammenfassung:The work presents the results of investigation of the influence of thermal cycling on ΔE effect as a function of the external magnetic field in amorphous [Fe.sub.64][Co.sub.21][B.sub.15] ribbons after thermomagnetic treatments in the temperature range of 250-350°C. The influence of the temperature of subsequent heating of ribbons in the temperature range 30-300°C on the absolute maximum value of the negative ΔE effect has been determined. The heating results in a displacement of maximum absolute value of negative ΔE effect to the region of lower magnetic fields. Based on the obtained results, it has been established that the dependence of the field of uniaxial anisotropy induced by thermomagnetic treatment on heating temperature in amorphous [Fe.sub.64][Co.sub.21][B.sub.15] ribbons is close to linear.
