摘要：

All ground states of finite disordered +/-J Ising systems on cubic lattices are calculated exactly and classified into different ground-state clusters. These clusters are investigated with respect to their size and their geometric extension. We interpret the results in terms of a dependence on the fraction of antiferromagnetic couplings by a concept of free spin chains and free turnable spin groups. (C) 1998 Elsevier Science B.V.
