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…
Quenched charge disorder in CuO2 spin chains: Experimental and numerical studies
R. Leidl, R. Klingeler, B. Buechner +2
We report on measurements of the magnetic response of the anisotropic CuO_2 spin chains in lightly hole-doped La_x (Ca,Sr)_14-x Cu_24 O_41, x>=5. The experimental data suggest that…
Two-dimensional anisotropic Heisenberg antiferromagnet in a field
M. Holtschneider, W. Selke, R. Leidl
The classical, square lattice, uniaxially anisotropic Heisenberg antiferromagnet in a magnetic field parallel to the easy axis is studied using Monte Carlo techniques. The model di…
Ising antiferromagnet with mobile, pinned and quenched defects
W. Selke, M. Holtschneider, R. Leidl
Motivated by recent experiments on (Sr,Ca,La)_14 Cu_24 O_41, a two-dimensional Ising antiferromagnet with mobile, locally pinned and quenched defects is introduced and analysed usi…
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…
Phase diagrams of a classical two-dimensional Heisenberg antiferromagnet with single-ion anisotropy
R. Leidl, W. Selke
A classical variant of the two-dimensional anisotropic Heisenberg model reproducing inelastic neutron scattering experiments on La_5 Ca_9 Cu_24 O_41 [M. Matsuda et al., Phys.Rev. B…
