The free energy functional is expanded in a series of components belonging to the primary and secondary order parameters. A low-temperature phase with the monoclinic P2/c symmetry is a result of condensation of two order parameters X_3 and \\Delta_5 . The temperature dependence of the shear elastic constant C_44 is derived and the mechanism of its softening is discussed.", "revisions": [ { "version": "v1", "updated": "2008-01-09T12:45:58.000Z" } ], "analyses": { "keywords": [ "verwey phase transition", "free energy functional", "secondary order parameters", "monoclinic p2/c symmetry", "shear elastic constant" ], "tags": [ "journal article" ], "publication": { "journal": "Journal of Physics Conference Series", "year": 2007, "month": "Dec", "volume": 92, "number": 1, "pages": "012164" }, "note": { "typesetting": "TeX", "pages": 4, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2007JPhCS..92a2164P" } } }
