![]() | Mattis, Daniel C. | Partially frustrated Ising models in two dimensions | We examine ordered, periodic, Ising models on a sq lattice at varying levels x of frustration. The thermodynamic singularity of the fully frustrated model (x=1) is at T=0 while those of partially frustrated lattices (0<x<1) occur at finite Tc . The critical indices in the partially frustrated latti... | Antiferromagnets; Frustration; Ising chain | 2003-06 |
