4-q MAGNETIC STRUCTURE OF NEODYMIUM
We have used two neutron-scattering techniques to investigate the magnetic structure of neodymium. By observations of harmonic combinations of its modulation vectors we have deduced that the low temperature magnetic structure is quadruple-q. We have confirmed this by observing a single domain of the structure in a suitably aligned magnetic field. For more than twenty years, the magnetic orderin...

متن کاملCrystal structure of demetallized concanavalin A: the metal-binding region.
\Ve llave determined the crystal structure of demetallized concanavalin A, at a resolution of 3.2 8, by rnolecnlar replacement using the knowd structure of native concanavalin A. Refinement of the initial model using a, constraint-restraint reciprocal-space least-squares procedure caused the conventional crystallographic agreement (11) factor t,o decrcase from 0.47 to a final valne of 0.26. The...
متن کاملCrystal structure of the mixed-metal thiophosphate Nb1.18V0.82PS10
The mixed-metal thio-phosphate, Nb1.18V0.82PS10 (niobium vanadium phospho-rus deca-sulfide), has been prepared though solid state reactions using an alkali-metal halide flux. The title compound is isostructural with two-dimensional Nb2PS10. [M 2S12] (M = Nb or V) dimers built up from two bicapped trigonal prisms and tetra-hedral [PS4] units share sulfur atoms to construct (1) ∞[M 2PS10] chains ...
متن کاملCrystal structure of the mixed-metal trisulfide BaCu1/3Ta2/3S3
The mixed-metal title compound, BaCu1/3Ta2/3S3 [barium copper(II) tantalum(V) tris-ulfide], was prepared through solid-state reactions. The crystal structure adopts the BaTaS3 structure type and consists of face-sharing [MS6] (M = Ta,Cu) octa-hedra (point-group symmetry -3m.) that are condensed into infinite chains along [001]. Adjacent chains are linked through the barium cations (site symmetr...
