Phase transitions of three dimensional frustrated Heisenberg systems in an applied magnetic field
A study of three dimensional frustrated Heisenberg systems in an applied magnetic field is presented. Both the stacked triangular lattice and the FCC Kagome lattice are considered. Monte Carlo methods are used to determine the phase diagrams for nearest neighbour antiferromagnetic exchange in the presence of an applied field. Finite size scaling is used to determine the critical exponents which characterize the various phase boundaries.
