Partial substitution of Ce in place of Y has been achieved by taking care of charge compensation and compounds with the general formula Y1-2xCexBa2+xCu3O6·5+δ have been successfully prepared. X-ray powder diffraction analysis reveals that this substitution gives orthorhombic single phase for 0⩽x⩽0·3. TheTc remains nearly unchanged between 94-90 K.
