The ground-state properties of the spin-1/2 RKKY Heisenberg spin glass are investigated on the fcc lattice. Numerical diagonalization of finite-size systems and extrapolation to the infinite system suggest either that the correlation function decays in a power law 〈S0·Sr2 ~ r–1–η (η = 0.02±0.09) or that there is a small but finite value of the order parameter. From comparison with other theories, we prefer the former possibility of vanishing spin glass ordering.
