The magnetic susceptibilities of RCu/sub 6/ compounds (R = rare earth) were measured over the temperature range 80 to 12O0 deg K. The contributions to the magnetic susceptibility were the Curie-Weiss term, expressing the paramagnetism of the localized felectrons and a temperature-independent term for which all the contributions have been estimated. The most important contribution to the temperature-independent term is given by an enhanced Pauli paramagnetism. An expression is proposed for calculating the enhancement factors of the Pauli paramagnetism. The anomalous behavior of the SmCu/sub 6/ compound results mainly from Van Vleck-type paramagnetism, and could adequately be calculated on the basis of free Sm/sup 3+/ ions, as in the case of the compound SmAl/sub 3/ (de Wijn, van Diepen and Buschow 1967).
