Nanoparticle La0.7Ca0.3MnO3 was synthesized for the first time by the glycine-nitrate method without additional heat treatment. The average crystallite size of similar to 10 nm obtained by both transmission electron microscopy and X-ray diffraction was among the smallest achieved by the combustion method. Magnetic measurements showed para-to-ferromagnetic transition temperature T-C = 120 K, saturation magnetization M-S = 46 emu g(-1) and transition of the spin-glass type at T-f = 95 K.
