Antiferromagnetic sawtooth chain with Heisenberg and Ising bonds
The sawtooth chain with pairs of S = 1/2 spins interacting with XXZ-interactions placed on each second tooth is considered. All other interaction bonds are taken to be of Ising type. Exact statistical mechanical solution of the model within the direct transfer-matrix technique is obtained. The sol...

| description |
The sawtooth chain with pairs of S = 1/2 spins interacting with XXZ-interactions placed on each second
tooth is considered. All other interaction bonds are taken to be of Ising type. Exact statistical mechanical
solution of the model within the direct transfer-matrix technique is obtained. The solution allows one to obtain
exact analytic expressions for all thermodynamic functions of the model. Ground state properties are also
investigated, the corresponding ground state phase diagram is presented. |
