Zusammenfassung

By a recursive method numerically exact free energies are calculated forL×L×M Ising lattices with random bonds andL=4, 4lEMlE10, applying free boundaries in the direction where the lattice is less small and otherwise periodic boundary conditions. Both for the±J model and the gaussian model the specific heat is in fair agreement with Monte Carlo results obtained for much larger lattices. However, ...
