Abstract
The spin-glass susceptibility is analyzed by the Coherent Anomaly Method (CAM) [1] applied to a series of closed-form approximations in the Cluster Variation Method (CVM) [2] for the random-bond Ising model on the square, cubic and hyper-cubic lattices. No spin-glass transition is obtained for the square lattice, while for the cubic lattice and higher dimensional lattices spin-glass transitions are obtained; the transition temperature and the exponent of the spin-glass susceptibility obtained for the cubic lattice are in good agreement with those by Monte Carlo simulations [3].
