abstract

  • The crystal structures of TbAsO4 and DyAsO4 have been determined by X rays, using single crystal diffraction techniques. The structures have been determined both above and below the co-operative Jahn–Teller phase transition temperature. The structures at room temperature are in good agreement with previous results. The low temperature structures, below the phase transition temperature, are compared to the theory of Elliott, Harley, Hayes, and Smith.
