  We investigate the self-organization of a binary mixture of similar sized
rods and dipolar soft spheres by means of Monte-Carlo simulations. We model the
interparticle interactions by employing anisotropic Gay-Berne, dipolar and
soft-sphere interactions. In the limit of vanishing magnetic moments we obtain
a variety of fully miscible liquid crystalline phases including nematic,
smectic and lamellar phases. For the magnetic mixture, we find that the liquid
crystalline matrix supports the formation of orientationally ordered
ferromagnetic chains. Depending on the relative size of the species the chains
align parallel or perpendicular to the director of the rods forming uniaxial or
biaxial nematic, smectic and lamellar phases. As an exemplary external
perturbation we apply a homogeneous magnetic field causing uniaxial or biaxial
ordering to an otherwise isotropic state.
