We report a simple synthesis process of the superconductor La(La0.15Ba0.85)2Cu3O7 by the conventional solid state reaction method in normal conditions of pressure and temperature. The X-ray powder diffraction (XRD) showed a polycrystalline sample and the analysis by Rietveld Refinement revealed that the structure stabilized into orthorhombic (Pmmm) phase (cell parameters a= 3.9075 Å, b= 3.9199 Å and c = 11.7433 Å).Magnetic moment measurement indicates that the compound is superconductor under the onset critical temperature (Tc) of 40 K.
