Abstract: By simulating the magnetic susceptibility,the CEF influence on the magnetic properties of Ce2CuxNi1-xGe6 is studied,the CEF splitting levels and the corresponding wave functions of Ce2CuxNi1-xGe6 are obtained.The CEF analytical results show that the six-fold ground states for Ce3+ are usually mixed doublet.The CEF splitting energies of Ce3+ become larger with the increase of the substitution x.The substitution of Cu for Ni results in a strong hybridization between the conduction electrons and f electrons an...
