Summary
Slope changes of the lattice constants and dc magnetization measurements as a function of the oxygen content of powder 123 samples, indicate the existence of three phases with phase boundaries at x ≅ 6.75 and x ≅ 6.91. In addition, a splitting of the derivative of the magnetization curve appears at x ≥ 6.95. These results are discussed in terms of a three-phase model. It is shown that oxygen inhomogeneities of the grains cannot be the reason for the double peaks in specific heat and magnetization.
