Abstract
We study a simple model for a wire which consists of alternate magnetic and non-magnetic segments. We are interested in the state of relative orientat ions of the disc-like magnetic segments. In particular, we investigated the ground state and the finite temperature phase diagram of the system, using ground state search, Mean field approximation and Monte Carlo simulations. We find a rich variety of orientational transitions. (C) 2000 Elsevier Sci ence B.V. All rights reserved.
