11. One order parameter represents a solid nanoparticle, while the other represents the liquid phase. 12. If the biasing potential is strictly a function of a reaction coordinate or order parameter " 13. The model calculates melting conditions as a function of two competing order parameters using Landau potentials. 14. However, note that order parameters can also be defined for non-symmetry-breaking transitions. 15. A domain is a spatially extended region with a constant direction and phase of its order parameters . 16. Here \ Delta is the amplitude of the order parameter , and \ theta is the phase. 17. The definition used the correlation of the local order parameter at different points in space and time. 18. An example of an order parameter is the net magnetization in a ferromagnetic system undergoing a phase transition. 19. Apart from single phase multiferroics, composites and heterostructures exhibiting more than one ferroic order parameter are studied extensively. 20. In multiferroic thin films, the coupled magnetic and ferroelectric order parameters can be exploited for developing magnetoelectronic devices.
