Spin- model with competing interactions on diamond-decorated lattices
D. V. Dmitriev, V. Ya. Krivnov, O. A. Vasilyev
We investigate the ground state properties, magnetization, and low-temperature thermodynamics of the ferromagnetic-antiferromagnetic spin- model on diamond-decorated lattices wi…
Frustrated spin models on two- and three-dimensional decorated lattices with high residual entropy
D. V. Dmitriev, V. Ya. Krivnov, O. A. Vasilyev
We study the ground-state properties of a family of frustrated spin-1/2 Heisenberg models on two- and three-dimensional decorated lattices composed of connected star-shaped units.…

D. V. Dmitriev, V. Ya. Krivnov, O. A. Vasilyev
We study the ground state properties of the anisotropic spin-1/2 Heisenberg model on lattices built from ideal diamond units with competing ferro- and antiferromagnetic interaction…
Macroscopic ground state degeneracy of the ferro-antiferromagnetic Heisenberg model on diamond-decorated lattices
D. V. Dmitriev, V. Ya. Krivnov, O. A. Vasilyev
We investigate the spin-1/2 Heisenberg model with competing ferromagnetic and antiferromagnetic interactions on diamond-decorated lattices. Tuning the exchange interactions to the…
Macroscopic degeneracy of ground state in the frustrated Heisenberg diamond chain
D. V. Dmitriev, V. Ya. Krivnov
The spin- Heisenberg diamond chain with ferro- and antiferromagnetic exchange interactions is studied. The phase boundary in the parametric space of these interactions…
Magnetic properties of ferro-antiferromagnetic spin triangle chain
D. V. Dmitriev, V. Ya. Krivnov
We study the frustrated spin- model consisting of a linear chain of triangles with ferro (F)- and antiferromagnetic (AF) interactions connected by ferromagnetic intera…
