Dysprosium-based experimental representatives of an Ising-Heisenberg chain and a decorated Ising ring
Dysprosium-based experimental representatives decorated Ising ring
2010/11/24
It is shown that the bond-decorated Ising model is a realistic model for certain real magnetic
compounds containing lanthanide ions. The lanthanide ion plays the role of Ising spin. The re-
quired c...
Effect of anisotropy on the field induced quantum critical properties of the three dimensional s=1/2 Heisenberg model
Effect of anisotropy field induced quantum critical properties
2010/11/18
The field induced quantum critical properties of the three dimensional spin-1/2 anisotropic antifer-romagnetic Heisenberg model has been studied. We have investigated the quantum phase transition betw...
Spin wave calculation of the field-dependent magnetization pattern around an impurity in Heisenberg antiferromagnets
Spin wave calculation field-dependent magnetization pattern Heisenberg antiferromagnets
2010/11/18
We consider the magnetic- eld dependent spatial magnetization pattern around a general impurity embedded in a Heisenberg antiferromagnet using both an analytical and a numerical spin wave approach. Th...
Magnetic phase diagram of spatially anisotropic, frustrated spin-1/2 Heisenberg antiferromagnet on a stacked square lattice
Magnetic phase diagram of spatially anisotropic stacked square lattice
2010/11/17
Magnetic phase diagram of a spatially anisotropic, frustrated spin- 12 Heisenberg antiferromagnet on a stacked square lattice is investigated using second-order spin-wave expansion.
Valence-bond crystal in the extended Kagomé spin-1/2 quantum Heisenberg antiferromagnet: A variational Monte Carlo approach
Valence-bond crystal extended Kagomé spin-1/2 quantum variational Monte Carlo approach
2010/11/24
The highly-frustrated spin-1=2 quantum Heisenberg model with both nearest (J1) and next-
nearest (J2) neighbor exchange interactions is revisited by using an extended variational space
of projected ...
Phase Structure of Anisotropic Antiferromagnetic Heisenberg Model on Layered Triangular Lattice: Spiral State and Deconfined Spin Liquid
Phase Structure Deconfined Spin Liquid
2010/10/27
In the present paper, we study spin- 1 2 antiferromagnetic (AF) Heisenberg model on layered anisotropic triangular lattice and obtain its phase structure. We use the Schwinger bosons for representing ...
