Uniaxially anisotropic antiferromagnets in a field on a square lattice
Classical uniaxially anisotropic Heisenberg and XY antiferromagnets in a field along the easy axis on a square lattice are analysed, applying ground state considerations and Monte Carlo techniques. The models are known to display antiferromagnetic and spin–flop phases. In the Heisenberg case, a single– ion anisotropy is added to the XXZ antiferromagnet, enhancing or competing with the uniaxial ...
متن کاملImaging bond order near nonmagnetic impurities in square-lattice antiferromagnets.
We study the textures of generalized "charge densities" (scalar objects invariant under time reversal), in the vicinity of nonmagnetic impurities in square-lattice quantum antiferromagnets, by order parameter field theories. Our central finding is the structure of the vortex in the generalized density wave order parameter centered at the nonmagnetic impurity. Using exact numerical data from qua...

متن کاملRobust metastable skyrmions and their triangular-square lattice structural transition in a high-temperature chiral magnet.
Skyrmions, topologically protected nanometric spin vortices, are being investigated extensively in various magnets. Among them, many structurally chiral cubic magnets host the triangular-lattice skyrmion crystal (SkX) as the thermodynamic equilibrium state. However, this state exists only in a narrow temperature and magnetic-field region just below the magnetic transition temperature Tc, while ...
