On the states of orientations along a magnetically inhomogeneous nanowire

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 orientations of the disc-like magnetic segments. In particular, we investigated the ground state and the "nite temperature phase diagram of the system, using ground state search, Mean "eld approximation and Monte Carlo simulations. We "nd a rich variety of orientational transitions.
