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.…
Phase diagram and macroscopic ground state degeneracy of frustrated spin-1/2 anisotropic Heisenberg model on diamond-decorated lattices
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…
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…
Spin triangle chain with ferromagnetic and antiferromagnetic interactions on the transition line
V. Ya. Krivnov, D. V. Dmitriev
We investigate spin- anisotropic model of a linear chain of triangles with competing ferro- and antiferromagnetic interactions and ferromagneic Heisenberg interactions…
Kagome-like chains with anisotropic ferromagnetic and antiferromagnetic interactions
D. V. Dmitriev, V. Ya. Krivnov
We consider a spin- kagome-like chain with competing ferro- and antiferromagnetic anisotropic exchange interactions. The ground state phase diagram of this model consi…
Ferrimagnetism in delta chain with anisotropic ferromagnetic and antiferromagnetic interactions
D. V. Dmitriev, V. Ya. Krivnov
We consider analytically and numerically an anisotropic spin- delta-chain (sawtooth chain) in which exchange interactions between apical and basal spins are ferromagne…
Delta chain with anisotropic ferromagnetic and antiferromagnetic interactions
D. V. Dmitriev, V. Ya. Krivnov
We consider analytically and numerically an anisotropic spin- delta-chain (sawtooth chain) with nearest-neighbor ferromagnetic and next-nearest-neighbor antiferromagne…
