Solution Growth and Investigation of the Single Crystals from the CePdIn System

We report on the investigation of recently discovered heavy fermion compounds within the Ce-Pd-In system. Single crystals of $Ce_{n}Pd_{m}In_{3n+2m}$ (n=2, 3, 5; m=1, 2) and $Ce_{4}Pd_{10}In_{21}$ were synthesized from In-flux. Specific heat measurements of the multiphase $Ce_{n}Pd_{m}In_{3n+2m}$ system revealed a superconducting transition at $T_{c}$=0.69 K arising from $Ce_{2}PdIn_{8}$ and another, magnetic transition at $T_{m}$=1.67 K arising from either $Ce_{3}PdIn_{11}$ or $Ce_{5}Pd_{2}In_{19}$. Low-temperature data of $Ce_{4}Pd_{10}In_{21}$ display ferromagnetic long-range order below 0.8 K.
