【 摘 要 】

We succeeded in growing single crystals of Ce2PtIn8and CePt2In7by In selfflux method. We performed the single crystal X-ray diffraction and determined the lattice parameters and atomic positions. We also obtained cubic-like crystals with the typical size of 1×1×1mm3, in which Ce2PtIn8thin layer grows on CeIn3 single crystal surface. This structure implies a peritectic growth of Ce2PtIn8on most likely the CeIn3 (100) surface. The electrical resistivity of CePt2In7shows sharp kink at the Neel temperature of 5.5 K, and exhibits the Fermi liquid behavior.
