Abstract
Polycrystalline La0.7-x Pr (x) Ba0.3MnO3 (0 a parts per thousand currency signxa parts per thousand currency sign 0.2) samples were prepared using solid-state reaction and checked by X-ray diffraction. Magnetization measurements versus temperature and applied magnetic field were used to investigate their magnetic properties. For samples with x= 0.2, the Griffiths phase is observed when the inverse of susceptibility (1/ chi vs. T) is analyzed.
