NON-EQUILIBRIUM THERMODYNAMICS IN WEISS MODEL OF FERRO-MAGNETS

Štefan Barta - Peter Dieška

   We derived a generalized Gibbs relation and an expression for entropy production. Using to the second law of thermodynamics stable and unstable thermodynamic branches on the magnetization curve were determined. A new insight into the phenomenological theory of phase transition was introduced.
