对CePdSn单晶的磁化强度和中子衍射测量结果表明，CePdSn中的4f电子处于Ce 3+局域态，在T N =7 K以下的磁结构与传播矢量q =（0，0.473，0）不相称. Ni取代Pd增强了CeNiSn中的近藤效应，导致了T-N的降低和4f电子的基态跃迁。
Experimental results of magnetization and neutron diffraction measurements on single-crystal CePdSn revealed that the 4f electrons in CePdSn are in a localized Ce 3+ state, and the magnetic structure below T N =7 K is incommensurate with the propagation vector of q =(0, 0.473, 0). Nickel substitution for Pd strengthens the Kondo effect, resulting in the decrease of T N and the nonmagnetic ground state of 4f electrons in CeNiSn.
