| Abstract: | A new ternary compound, Ce2PdGa10, has been synthesized using Ga flux and characterized by single-crystal X-ray diffraction. Ce2PdGa10 adopts a tetragonal structure in the I4/mmm space group and is isostructural to Ce2NiGa10. Lattice parameters are  ,  ,  , and Z=2. The compound is metallic (dρ/dT>0), with the resistance decreasing roughly linearly with temperature from 300 to 175 K. The magnetic susceptibility of Ce2PdGa10 is consistent with local-moment paramagnetism and no long-range magnetic ordering occurs down to 2 K. A large positive magnetoresistance over 200% is observed at 2 K for fields of 9 T. In this paper, we present the structure and physical properties of Ce2PdGa10 and compared them to CePdGa6. |
