R 0 . 7 Pb 0 . 3 MnO 3 (R=Nd and La) single crystals with perovskite-like structure were prepared by the flux growth using the accelerated crucible rotation technique. Large crystal volume of 1.1x0.7x0.4cm 3 was obtained. The low-temperature magnetization behavior and magnetic structure were studied. It was found that the temperature dependence of magnetization of both the samples obeys the Bloch T 3 / 2 law. However, Nd 0 . 7 Pb 0 . 3 MnO 3 single crystals exhibited larger B value, larger high-field susceptibility at low temperature, and lower Curie temperature than La 0 . 7 Pb 0 . 3 MnO 3 samples. The influence of Nd on magnetic properties is discussed.
