Abstract
The system with two order parameters is investigated theoretically. This system is described by Landau model with a biquadratic coupling between the two order parameters, each of which involves the second order phase transition. Phases which can result from competition between the order parameters are found, and phase diagrams are shown. Transition structure among the phases and thermodynamical properties in the phases are investigated. Application to magnetic system is discussed.Keywords
