Phase diagrams of the Ising-Heisenberg chain with S=1/2 triangular XXZ clusters

Abstract

The one dimensional spin system consisted of triangular $S=1/2$ $XXZ$ Heisenberg clusters alternating with single Ising spins is considered. Partition function of the system is calculated exactly within the transfer--matrix formalism. T=0 ground state phase diagrams, corresponding to different regions of the values of system parameters are obtained.
