Title: Pseudosymmetric features of non-centrosymmetric AB type crystals

Abstract

This work is supplement to our previous investigation (Gazhulina and Marychev, 2015) [1]. We have considered pseudosymmetric features with respect to the operation of inversion (pseudoinversion) for 340 non-centrosymmetric AB type crystals. Analysis of the features of particular structure types allowed us to determine the positions of pseudoinversion centers, subdivide them into separate types, and classify the entire set of crystals studied with respect to the types of pseudoinversion centers and peculiarities of the behavior of the degree of pseudoinversion depending on the ratio of atomic numbers of A and B components. For each group of crystals, average values and lower boundaries of the maximum pseudoinversion are determined and distribution with respect to the degree of pseudoinversion is constructed. - Graphical abstract: A group of 340 non-centrosymmetric AB type crystals have been considered for their pseudosymmetry features with respect to the operation of inversion. Positions of pseudoinversion centers, subdivision of them into separate types, classification of the entire set of crystals studied with respect to the types of pseudoinversion centers and peculiarities of the behavior of the degree of pseudoinversion are established and discussed. Display Omitted - Highlights: • We consider pseudoinversion of 340 non-centrosymmetric AB type crystals. • ABmore » type crystals are divided into three groups with respect to pseudoinversion. • Positions and types of pseudoinversion centers are determined. • Lower boundaries of the maximum pseudoinversion are determined.« less

  • The new compound (IrCe{sub 3})I{sub 3} was synthesized by comproportionation reactions of stoichiometric ratios of CeI{sub 3}, Ce and Ir. Single crystal X-ray diffraction structure determination shows that (IrCe{sub 3})I{sub 3} crystallizes with the cubic variant of the (TR{sub 3})X{sub 3} family (I4{sub 1}32, Z=8, a=12.450(1) Å, V=1930.0(3) Å{sup 3}) and is isostructural with the recently reported (RuLa{sub 3})Br{sub 3}. Octahedral (IrCe{sub 6}) clusters share three common edges forming interpenetrating chains that run along the 4{sub 1} screw axes. Magnetic measurements on pure powder samples of (IrCe{sub 3})I{sub 3} show paramagnetic behavior and, at temperatures below 2 K, a mictomagneticmore » state. The isostructural (RuLa{sub 3})Br{sub 3} is a Pauli paramagnet suggesting metallic conductivity which is consistent with band structure calculations where the Fermi level is placed below a pseudogap. For (IrCe{sub 3})I{sub 3}, on the contrary, the Fermi level falls in a narrow gap rather than a pseudogap suggesting activated conductivity. - Graphical abstract: The subtle change from (RuLa{sub 3})Br{sub 3} to (IrCe{sub 3})I{sub 3} (IrCe{sub 3})I{sub 3} with the addition of one 5d and one 4f electron changes the magnetic and electronic properties dramatically; (RuLa{sub 3})Br{sub 3} is a Pauli paramagnet, (IrCe{sub 3})I{sub 3} a Langevin paramagnet with mictomagnetic behavior at very low temperatures.

  • Special features of noncollinear Bragg diffraction of light from ultrasound in centrosymmetric cubic crystals placed in an external electric field are considered. Particular cases of acousto-electro-optical interaction on (quasi-)longitudinal and (quasi-)transverse acoustic waves propagating the (001) and (110) planes are analyzed. The dependence of diffracted light energy characteristics on photoelastic and electro-optical parameters of a cubic centrosymmetric crystal, as well as external field strength and orientation, is determined. 11 refs., 2 figs.
  • We demonstrate that parity-nonconserving interaction due to the nuclear weak charge Q{sub W} leads to a nonlinear magnetoelectric effect in centrosymmetric paramagnetic crystals. It is shown that the effect exists only in crystals with special symmetry axis k. Kinematically, the correlation (correction to energy) has the form H{sub PNC}{proportional_to}Q{sub W}E{center_dot}[Bxk](B{center_dot}k), where B and E are external magnetic and electric fields. This gives rise to the magnetic induction M{sub PNC}{proportional_to}Q{sub W}{l_brace}k(B{center_dot}[kxE])+[kxE](B{center_dot}k){r_brace}. To be specific, we consider rare-earth-metal trifluorides and, in particular, dysprosium trifluoride which looks the most suitable for experiment. We estimate the optimal temperature for the experiment to be ofmore » a few kelvin. For the magnetic field B=1 T and the electric field E=10 kV/cm, the expected magnetic induction is 4{pi}M{sub PNC}{approx}0.5x10{sup -11}G, six orders of magnitude larger than the best sensitivity currently under discussion. Dysprosium has several stable isotopes, and so comparison of the effects for different isotopes provides the possibility for precise measurement of the Weinberg angle.« less
  • We demonstrate polarity-sensitive orientation mapping of non-centrosymmetric phases by Electron Backscatter Diffraction (EBSD). The method overcomes the restrictions of kinematic orientation determination by EBSD, which is limited to the centro-symmetric Laue-groups according to Friedel's rule. Using polycrystalline GaP as an example, we apply a quantitative pattern matching approach based on simulations using the dynamical theory of electron diffraction. This procedure results in a distinct assignment of the local orientation according to the non-centrosymmetric point group of the crystal structure under investigation.
