【 摘 要 】

The Neel temperatures, T(sub N), of Tb(of Tb(sub x)Er(sub 1-x)Ni(sub 2)B(sub 2)C) samples have been determined from the temperature dependence of magnetization measurements. A breakdown of the de Gennes scaling of T(sub N) with a clear turning point around x=0.45 has been observed. The T(sub N) values of Tb(sub x)Er(sub 1-x)Ni(sub 2)B(sub 2)C do not change much within the range of O
