| Abstract: | In this paper, we simulate the temperature dependence of the inverse magnetic susceptibility of the same symmetry compounds CePdGa3, Ce3Ag4Ge4 and Ce3Ag4Sn4 by taking into account the crystalline electric field (CEF) effect. Through this calculation, we obtain the CEF splitting levels and the corresponding wave functions of them and analysis the CEF influence on the rare earth ion ground states. The CEF scheme suggests that the multiple ground state of Kramers ion Ce3+ become three doublets with the orthorhombic CEF. |
