We have obtained Lal.9~Bio.osCuO4+ ~ with various values of 8 by the KMnO 4 oxidation method. The largest value of = 0.136 is about twice as large as that obtained by annealing under high pressures of oxygen, B = 0.056. A structural phase transition from the orthorhombic to the tetragonal phase with
