" /> Verwey transition - CISMeF





Preferred Label : Verwey transition;

IUPAC definition : An electron-ordering transition occurring in a mixed-valent system that results in an ordering of formal valence states in the low-temperature phase. Example: The prototype system, first identified by Verwey, is the ferrospinel magnetite, Fe sup 3 /sup [Fe sup 3 /sup Fe sup 2 /sup ]O sub 4 /sub in which an ordering of Fe sup 3 /sup and Fe sup 2 /sup ions within octahedral sites is thought to occur below T v 120 K.;
