On the Ising-Heisenberg model with the doubly decorated network structure I

Jozef Strecka, Michal Jascur

Published 2003-04-14Version 1

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 interaction parameters are ferromagnetic, we found in addition to an usual ferromagnetic phase another two phases with a nontrivial long-range order.
