Triangular antiferromagnetic Ising model
We solve the Ising problem on a triangular lattice with anisotropic interactions. Special consideration is given to the antiferromagnetic case. It is found that no phase transition exists if J1=J2=J3<0. Allowing a slightly different value of one of the coupling constants J3, we find k Tcf2(|J1|-|...
