Spin-1 Heisenberg antiferromagnetic chain with exchange and single-ion anisotropies
D. Peters, I. P. McCulloch, W. Selke
Using density matrix renormalization group calculations, ground state properties of the spin-1 Heisenberg chain with exchange and single-ion anisotropies in an external field are s…
Uniaxially anisotropic antiferromagnets in a field along the easy axis
W. Selke, M. Holtschneider, R. Leidl +2
Uniaxially anisotropic antiferromagnets in a field along the easy axis are studied with the help of ground state considerations and Monte Carlo simulations. For classical models, t…
Biconical structures in two-dimensional anisotropic Heisenberg antiferromagnets
M. Holtschneider, W. Selke
Square lattice Heisenberg and XY antiferromagnets with uniaxial anisotropy in a field along the easy axis are studied. Based on ground state considerations and Monte Carlo simulati…
Ising and anisotropic Heisenberg magnets with mobile defects
M. Holtschneider, R. Leidl, W. Selke
Motivated by experiments on (Sr,Ca,La)_14 Cu_24 O_41, a two-dimensional Ising model with mobile defects and a two-dimensional anisotropic Heisenberg antiferromagnet have been propo…
