© 2016 Elsevier B.V. We succeeded in growing five new single crystalline compounds RPt2Cd20(R = La, Ce, Pr, Nd, and Sm) by the Cd self-flux method. These compounds are found to crystallize in the cubic CeCr2Al20-type crystal structure by the X-ray diffraction using single crystals. We measured the electrical resistivity, magnetic properties, and specific heat for all compounds. The resistivity for R = Ce, Nd, and Sm indicates an abrupt decrease, which might correspond to a magnetic transition. It is suggested that the ground state of CePt2Cd20is Γ7doublet from the magnetization measurement. The magnetization of PrPt2Cd20shows a metamagnetic behavior at 1.6 T in the paramagnetic state, which could be due to the crystalline electric field effect with non-Kramers Γ3doublet or Γ1singlet ground state. The contribution of optical phonon modes to the lattice specific heat is discussed in LaPt2Cd20.
