Dipolar interaction in a 1-D Ising ring

<div>The effects of a long-range interaction in a one-dimensional (1D) magnetic ring is studied. In this work, the Monte Carlo method is employed to obtain the equilibrium state of a modified quasi-1D Ising model having a dipolar interaction in a ring geometry. At low temperatures (<em>T</em>), the behavior of the magnetization (<em>M</em>) as a function of <em>T</em> is shown to depend on the strength of the dipolar interaction <em>(G)</em>.
