| Description | Journal: Journal of Physics C: Solid State Physics The existence of a re-entrant ferromagnetic phase seems to be a general characteristic of systems with frustration and disorder even when no spin-glass phase exists. Using two different methods-the finite-cluster approximation and a new renormalisation technique-the authors studied a two-dimensional nearest-neighbour random-interaction Ising model in which the interactions are independent random variables distributed according to the following law: $P(K_{ij}$)=p delta $(K_{ij}$-K)+(1-p) delta $(K_{ij}$-aK) where K>0 and mod a mod |
