For SmCj, as mentioned above, the reciprocal susceptibility does not obey the Curie-Weiss law above the Neel temperature of 21 K (Sakai et al. 1981a) in contrast to the results of Vickery et al. (1959). This anomalous magnetic behavior resembles that reported for other samarium compounds and seems to be attributed to the contribution of the first excited multiplet state (J = j) to the value.
