Abstract
$SrPd_2Ge_2$ single crystals were grown by self-flux method. Several shiny plate-like single crystals were obtained. The crystal structure and lattice parameters were characterized using the x-ray diffractometor, which indicates the crystals are in a single phase of $ThCr_2Si_2$-type. We confirmed superconducting transition temperature at 2.7 K by measuring magnetization and electrical resistivity.
