  We report a Monte Carlo simulation of deposition of magnetic particles on a
one-dimensional substrate. Incoming particles interact with those that are
already part of the deposit via a dipole-dipole potential. The strength of the
dipolar interaction is controlled by an effective temperature $T^*$, the case
of pure diffusion-limited deposition being recovered in the limit
$T^*\to\infty$. Preliminary results suggest that the fractal dimension of the
deposits does not change with temperature but that there is a
(temperature-dependent) cross-over from regimes of temperature-dependent to
universal behaviour. Furthermore, it was found that dipoles tend to align with
the local direction of growth.
