We succeeded in growing single crystals of Yb 4Sb 3, Ullmannite(NiSbS)-type compounds, Pd 3Bi 2Si 2, EuPtSi, and EuPtGe with the non-centrosymmetric cubic structures by the Bridgman method. Split Fermi surface properties are clarified for Yb 4Sb 3 and Pd 3Bi 2Si 2. As for EuPtSi and EuPtGe with the cubic chiral structure, we observed the first-order like antiferromagnetic ordering at the Néel temperatures TN=4.0K and 3.4 K, respectively, which are small in magnitude compared with ordering temperatures of 10–100 K in the usual divalent Eu compounds, reflecting the frustration of spins in the chiral structure.
