The authors report here their results on magnetization study of amorphous Co{sub 100{minus}x}B{sub x} ribbons with 20 {le} x {le} 30 at.% B in the temperature range 10 K to 800 K and in applied magnetic field 5 {times} 10{sup 3} A/m. The thermomagnetization curve is found to obey the Bloch law, M{sub s}(T) = M{sub s}(0)(1{minus}{beta}T{sup 3/2}{minus}{gamma}T{sup 5/2}), spin wave stiffness constant and the range of the exchange interaction were calculated from the experimental results. They have found that the B content has a strong effect on stiffness constant D.
