We report a Monte Carlo study of the classical antiferromagnetic Heisenberg model on the triangular lattice. The free-energy cost for the formation of free vortices is obtained from a vorticity modulus. Evidence of a Kosterlitz-Thouless type of defect-mediated phase transition at a finite temperature is found.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
