Single crystals of Cu13Ba were successfully grown out of Ba-Cu self flux. Temperature dependent magnetization, M(T), electrical resistivity, rho(T), and specific heat, C-p(T), data are reported. Isothermal magnetization measurements, M(H), show clear de Haas-van Alphen oscillations at T = 2 K for applied fields as low as mu H-0-1T. An anomalous behavior of the magnetic susceptibility is observed up to T approximate to 50 K reflecting the effect of de Haas-van Alphen oscillations at fairly high temperatures. The field-and temperature-dependencies of the magnetization indicate the presence of diluted magnetic impurities with a concentration of the order of 0.01 at.%. Accordingly, the minimum and lower temperature rise observed in the electrical resistivity at and below T = 15 K is attributed to the Kondo-impurity effect.
