Abstract :
The temperature dependence of zero-field spontaneous magnetization of amorphous CoxSi5B95-x (x=70, 74, 78) alloys is investigated. The saturation magnetization is determined by linear extrapolation of the magnetization as a function of the internal magnetic field in the temperature range 4.2 K2 plays a significant role in thermal demagnetization.
