Abstract
An anisotropic triangular nearest-neighbor Ising model, with antiferromagnetic interactions, was studied. The phase diagram as a function of temperature and magnetic field was determined with the use of symmetry analysis, free-fermion approximation, phenomenological renormalization group, and Monte Carlo simulation. A massless phase, a Lifshitz point, and transition lines to commensurate phases were identified.
