The investigation of the cooperative Jahn-Teller effect has been given greater attention of late, both as a result of the increased theoretical interest in the general problem of phase transition, and as a result of the recent observation of a number of new rare-earth compounds having a structural phase transition at low temperatures because of this effect (e.g., DyVO^ [1]).
