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…

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…
