摘要
We have studied the intermetallic compound CeFe2 in Laves phase using a discrete variational method. The iron and cerium moments are antiparallel. The magnetization falls off rapidly when Al is substituted at the Fe site but only a small reduction in moments is noticed for Mn substitution. The calculated results are in agreement with recent experiments. The partial density of states is plotted to understand the nature of hybridization responsible for this anomalous magnetic behavior.
