The spin precession curves were measured from room temperature up to 873 K. Two sites are occupied by probes and the temperature dependence of both indicates a continuous phase transition at about 625 K. One site is ordered while the other is disordered. This situation is analyzed in terms of simple models already applied to perovskites. The transition temperature of the solid solution Bi2-xTexSrNb2-xHfxO9 (with 0 <= x <= 0.5) shows a strong dependence on composition. (c) 2006 Elsevier Ltd. All rights reserved.
