Title: Incommensurate Structure of Phosphorus Phase IV

Abstract

There are six known phases for phosphorus at room temperature under high pressure. Only the structure of phase IV, which exists from 107 GPa to 137 GPa, remains unsolved. We performed a powder x-ray diffraction experiment and a Rietveld analysis and successfully determined its structure to be an incommensurately modulated structure by only 1 site of atomic position. High-pressure phases of halogens and chalcogens have previously been shown to have a similar modulated structure; however, phosphorus phase IV is different from them and was shown to be the third case.

  • Zr was added to Cu-Zn-Al shape memory alloy as a grain refinement element. There are two new phases, Cu{sub 50.2}Zr{sub 24.6}Al{sub 17.3}Zn{sub 7.9} (at%) (Z{sub 1} phase) and Cu{sub 57.4}Zr{sub 20.4}Zn{sub 10.3}Al{sub 11.9} (at%) (Z{sub 2}) phase is studied in detail in the present paper. The results of electron diffraction and high-resolution electron microscopy (HREM) investigations indicated a one-dimensional incommensurate modulated structure in the Z{sub 2} phase. The average structure of the phase is base-centered orthorhombic. The systematic reflection conditions associated with the main and satellite reflections demonstrate that the Bravais class of the Z{sub 2} phases is P{sub 11{barmore » 1}}{sup Cmmm} type in a (3 + 1) dimensional space for the incommensurate modulated structure. The substitution modulation effects of the Al and Zr elements are revealed by energy-filtered transmission electron microscopy (EFTEM), {l_brace}1{bar 3}{bar 2}{r_brace} compound-type twins are observed in the Z{sub 2} phase. The relationship between the Z{sub 1} and Z{sub 2} phases in the alloy is discussed.« less
  • Inelastic neutron scattering experiments have been performed on lightly doped La{sub 1.975}Sr{sub 0.025}CuO{sub 4}, which contains a hole concentration slightly higher than the critical concentration for three-dimensional long-range antiferromagnetic order. We previously found that the magnetic excitation spectrum in the insulating phase with a diagonal incommensurate spin modulation has similarities to that in the superconducting regime, where the spin modulation is bond parallel. In this study, we investigate the excitations in detail around E{sub cross}, at which the excitations become most nearly commensurate. It is found that both the magnitude and the anisotropy of the momentum width of the excitationsmore » change abruptly at E{sub cross}. Our experimental results suggest that the magnetic excitations rising from the pair of (diagonally) incommensurate wave vectors merge at E{sub cross} into isotropic excitations.« less
  • Optical properties and phase transitions of (Pb{sub 1−1.5x}La{sub x})(Zr{sub 0.42}Sn{sub 0.40}Ti{sub 0.18})O{sub 3} (PLZST 100x/42/40/18) ceramics with different compositions have been investigated by temperature dependent spectroscopic ellipsometry. Two interband critical points (E{sub cp1} and E{sub cp2}) located at about 3.9 and 5.1 eV can be obtained by fitting standard line shapes to the second derivatives of the complex dielectric functions. Based on the band-to-band transitions, the phase diagram of PLZST ceramics can be well presented. Moreover, a peculiar incommensurate antiferroelectric state has been found to exist above the temperature of the normal commensurate antiferroelectric tetragonal structure. It can be stable belowmore » Curie temperature, evolving slowly with decreasing temperature towards the commensurate structure, which is due to strong pinning of incommensurate domain walls. The phenomena can result from a competition between ferroelectric ordering and antiferroelectric ordering caused by the lanthanum modification.« less
  • IR and Raman spectra of Ca{sub 2}MgSi{sub 2}O{sub 7}, Ca{sub 2}ZnSi{sub 2}O{sub 7} and Sr{sub 2}MgSi{sub 2}O{sub 7} oriented single crystals and powders have been measured. The temperature dependence of phonons has been established in the 4-650 K range. Discussion of the results has been performed on the basis of factor group approach for the tetragonal P4-bar 2{sub 1}m (D{sub 2d}{sup 3}) space group with Z=2. The assignment of the bands observed to the internal and external modes has been made on their polarization behaviour, phonon energy calculations and literature data. The evidences of the LO-TO splitting and commensurate (C)more » to incommensurate (IC) as well as incommensurate (IC) to normal (N) phase transitions have been found. As a representative example, the results obtained for the spontaneous Raman scattering have also been used in the discussion of the stimulated Raman spectra of Ca{sub 2}ZnSi{sub 2}O{sub 7}. - Graphical abstract: Raman and IR spectra of Ca{sub 2}MgSi{sub 2}O{sub 7}, Ca{sub 2}ZnSi{sub 2}O{sub 7}, Sr{sub 2}MgSi{sub 2}O{sub 7} have been measured. The temperature dependence of phonons has been established in the 4-650 K range.

  • The authors report a new structure determination of the Sr{sub 1.2872}NiO{sub 3} incommensurate composite hexagonal perovskite compound. Three different refinement strategies are presented: (1) a 3D supercell approximation with a nonharmonic development of the atomic displacement factor, (2) an original (3+1)D incommensurate composite description with the use of crenel functions, and (3) a (3+1)D commensurate composite model. The three strategies are discussed and compared to previous refinements carried out for the hexagonal perovskites in a classical way or with the superspace group formalism. Out of the three methods, the incommensurate composite approach gives slightly better results with a final globalmore » R value of 2.89% for 635 independent reflections and only 60 parameters (R{bar 3}m(00{gamma})Os) superspace group. The use of crenel functions notably improves previously reported results. New structural features are evidenced for Sr{sub 1.2872}NiO{sub 3}: (1) an incommensurate character, (2) a splitting of the trigonal prismatic nickel atoms over 5 positions, (3) a definite stoichiometry which induces a perfect charge balance, and (4) a nonharmonic behavior of some Sr atoms. Those characteristics seem general to most hexagonal perovskite compounds and essential for correctly interpreting their interesting magnetic properties. Finally, a new generic formulation is proposed, which explains the various stoichiometries observed and suggests a new compound possibility.« less
