Thermodynamics of layered Heisenberg magnets with arbitrary spin
I. Juhász Junger, D. Ihle, J. Richter
We present a spin-rotation-invariant Green-function theory of long- and short-range order in the ferro- and antiferromagnetic Heisenberg model with arbitrary spin quantum number S…
Thermodynamics of Heisenberg ferromagnets with arbitrary spin in a magnetic field
I. Juhász Junger, D. Ihle, L. Bogacz +1
The thermodynamic properties (magnetization, magnetic susceptibility, transverse and longitudinal correlation lengths, specific heat) of one- and two-dimensional ferromagnets with…
Thermodynamics of S>=1 ferromagnetic Heisenberg chains with uniaxial single-ion anisotropy
I. Juhász Junger, D. Ihle, J. Richter
The thermodynamic properties of S>=1 ferromagnetic chains with an easy-axis single-ion anisotropy are investigated at arbitrary temperatures by both a Green-function approach, base…
Green's-function theory of the Heisenberg ferromagnet in a magnetic field
I. Junger, D. Ihle, J. Richter +1
We present a second-order Green's-function theory of the one- and two-dimensional S=1/2 ferromagnet in a magnetic field based on a decoupling of three-spin operator products, where…
