Abstract

The ldquoTransfermatrix-Methodrdquo [1, 2] has been adapted to evaluate also the free energy of triangular 2–d-Ising lattices. The present work considers a model with nearest-neighbour antiferromagnetic couplings and a fraction 1–x of spins removed at random sites leading to some frustration effects. It is not yet clear if such a system shows spinglass behaviour [3, 4]. The correlation function ...
