To better understand the phase diagram for XY spins on the fully frustrated triangular lattice, we generalize that model, giving one class of bonds a ``tunable'' strength -\ensuremath{\eta}J, where \ensuremath{\eta}=1 gives the conventional model. As

The mean‐field phase diagram for an XY model on a square lattice is studied. At low temperatures, noncollinearity can be produced by individual ‘‘strong’’ impurity bonds or a finite concentration of ‘‘weak’’ impurity bonds. Thermal

The onset of spin canting due to the interaction of defect bonds has been studied by numerical calculation, continuum theory, and discrete lattice theory. This model is relevant to the problem of canting in amorphous ferromagnets. For a square lattic

The onset of canting for a ferromagnet with one and two antiferromagnetic defect bonds has been studied analytically. For individual negative defect bonds which are unable to cause canting, there is a long-range effective dipolar-like interaction whi
