Abstract
Amorphous Co1-xTbx ribbons with x = 0.45, 0.55 and 0.65 have been prep ared by melt spinning technique. Magnetization measurements were carri ed out at 4.2 K, under magnetic fields up to 150 kOe. The Co moment is found to be very small and the Tb moment is 7.15 mu(B) at 4.2 K, whic h indicates a speromagnetic spin structure. Using Chudnovsky's theory we have extracted some fundamental magnetic parameters.
