Centrosymmetric and pseudo-centrosymmetric structures refined as non-centrosymmetric.

The behaviour of the Flack parameter for centrosymmetric and pseudo-centrosymmetric crystal structures based on crystal structures published as being non-centrosymmetric is presented. It is confirmed for centrosymmetric structures that the value obtained for the Flack parameter is critically dependent on the Friedel coverage of the intensity data, approaching 0.5 for a coverage of 100% and stic...

Magnetic field dependence of the superconducting gap node topology in non-centrosymmetric CePt3Si

Non-centrosymmetric superconductors, such as CePt3Si and Li2PtB2, are believed to have a line node in the energy gap arising from coexistence of s-wave and p-wave pairing. Using as an example CePt3Si we show that a weak c-axis magnetic field will remove this line node, since it has no topological stability against time-reversal symmetry breaking perturbations. Conversely a field in the a − b pl...

Non-centrosymmetric Na3Nb4As3O19

A new non-centrosymmetric compound, tris-odium tetra-niobium triarsenic nona-deca-oxide, Na(3)Nb(4)As(3)O(19), has been synthesized by a solid-state reaction at 1123 K. The structure consists of AsO(4) tetra-hedra and NbO(6) octa-hedra sharing corners to form a three-dimensional framework containing two types of tunnels running along the c axis, in which the sodium ions are located. Na(+) catio...

Non-centrosymmetric Heavy-Fermion Superconductors

In this chapter we discuss the physical properties of a particular family of non-centrosymmetric superconductors belonging to the class heavy-fermion compounds. This group includes the ferromagnet UIr and the antiferromagnets CeRhSi3,CeIrSi3,CeCoGe3,CeIrGe3 and CePt3Si, of which all but CePt3Si become superconducting only under pressure. Each of these superconductors has intriguing and interest...

Non-centrosymmetric Ce3OCl[AsO3]2

The arsenite chloride Ce3OCl[AsO3]2 was synthesized in the form of colorless crystals from arsenic and cerium dioxide in a NaCl / KCl flux at 850 ◦C. Ce3OCl[AsO3]2 crystallizes with the noncentrosymmetric tetragonal Gd3OCl[AsO3]2 type, space group P42nm. The structure was refined from single crystal diffractometer data: a = 12.8590(6), c = 5.5627(3) Å, wR2 = 0.0429, 1463 F2 values, and 65 varia...
