Ferroelastic phase transition in TlH2PO4 has been investigated by means of neutron diffraction using single-crystal sample. The average structures of TlH2PO4 in the phases I and II have been determined. The crystal analysis with anisotropic thermal parameters in the phase I has been carried out for the 2-site model of O atom that the oxygen atoms forming the PO4 tetrahedron are disorder while other atoms are order. The result means that the ferroelastic phase transition is mainly caused by the rotational motion of PO4 tetrahedra. [ABSTRACT FROM AUTHOR] |
