Abstract

Single crystals of PrOs₄Sb₁₂ were grown by the Sub-flux method. Measurements of electrical resistivity and ac susceptibility confirmed a SC transition at T_c=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.
