Spin Frustration in an Exactly Solvable Ising-Heisenberg Diamond Chain
Michal Jascur, Jozef Strecka
Exact results of a mixed spin-1/2 and spin-1 Ising-Heisenberg diamond chain are obtained applying a generalized decoration-iteration transformation. Depending on the values of exte…
On the Ising-Heisenberg model with the doubly decorated network structure I
Jozef Strecka, Michal Jascur
Using an exact mapping transformation method, magnetic properties of a spin-1/2 and spin-1 doubly decorated Ising-Heisenberg model are investigated in detail. By assuming that both…
Unusual quantum phase in exactly solvable doubly decorated Ising-Heisenberg models
Jozef Strecka, Michal Jascur
Ground-state properties of the spin-1/2 and spin-1 Ising-Heisenberg model on doubly decorated planar lattices, are investigated in detail. On the basis of the mapping transformatio…
Existence of the magnetization plateau in a class of exactly solvable Ising-Heisenberg chains
Jozef Strecka, Michal Jascur
The mapping transformation technique is applied to obtain exact results for the spin-1/2 and spin-S (S=1/2,1) Ising-Heisenberg antiferromagnetic chain in the presence of an externa…
