Popis:	An Ising spin-glass calculation is presented showing that stable "reentrant" spin-glass behavior, which is absent in mean-field theory, occurs when local correlations are taken into account. The method is a simple Kikuchi approximation starting from the exactly soluble classical spin-glass model proposed by van Hemmen. The resulting phase diagram is in good agreement with experiment. ispartof: Physical Review B, Condensed Matter vol:30 issue:1 pages:495-497 status: published
