A simple model of liquid-crystalline magnetic suspension of anisometric particles

- We propose a simple statistical model of ferronematic liquid crystals.
- We use spherical approximation to derive equations of state.
- We study magnetic field induced order-disorder transitions.

On the base of molecular-statistical approach we study the phase transition between the ordered (ferromagnetic) and disordered (paramagnetic) phases in liquid-crystalline suspensions of magnetic nanoparticles in an external magnetic field. The free energy and equations of magnetic and orientational equilibrium are obtained in the framework of spherical approximation.
