Abstract: The stability conditions for replica-generated solutions of Ising spin glass models with general spin magnitude (S), anisotropy energy and gaussian distributed exchange are derived and discussed. The phase diagrams for integer S and half-integer S are argued to be qualitatively different when the anisotropy constant is negative. The spin glass phase (without symmetry breaking) of the S=1 model is shown to be everywhere unstable and the authors argue that the symmetric solution yields wrong first-order transition lines.
