Contribution à l'étude des transitions de phase dans les systèmes magnétiques désordonnes et dans les solutions micellaires

Abstract

Another term of the enery is adjusted on the Shnidman-Zia Hamiltonian for the micellar binary solutions in order to obtain the lamellar phase on the phase diagrams. Phase diagrams of the new hamiltonian is détermined where the lamellar phase appear via the mean field approach.
