Abstract

Single crystals of PrOs4Sb12 were grown by the Sub-flux method. Measurements of electrical resistivity and ac susceptibility confirmed a SC transition at Tc=1.85 K. The observation of the de Haas-van Alphen oscillations ensures the high quality of the samples. For the 121,123Sb NQR measurements, the single crystals were crushed into powder.
