Radio-frequency electric-dipole transitions between nearly degenerate, opposite parity levels of atomic dysprosium (Dy) were monitored over an eight-month period to search for a variation in the fine-structure constant, α. The data provide a rate of fractional temporal variation of α of (−2.7±2.6)×10 −15 yr −1 or a value of (−8.7 ± 6.6) × 10 −6 for kα, the variation coefficient for α in a chang...

We report the in situ formation of two novel metal-organic frameworks based on terbium and dysprosium ions using azobenzene-4,41-dicarboxylic acid (H2abd) as ligand, synthesized by soft hydrothermal routes. Both materials show isostructural three-dimensional networks with channels along a axis and display intense photoluminescence properties in the solid state at room temperature. Textural prop...

The growth of small tellurium clusters in helium and the influence of a metal impurity (dysprosium atoms) on the cluster size distribution are investigated in a double laser vaporization source. A model describing the role of the carrier gas as collision partner is presented, emphasizing the crucial influence of the gas pressure on cluster formation. Changes in cluster reactivity due to dyspros...

A simple trinuclear dysprosium complex shows complex slow relaxation of the magnetisation.

The title complex, [Dy(C(8)H(6)NO(4))(C(2)O(4))(H(2)O)](n), is a dysprosium coordination polymer with mixed anions and was obtained under hydrothermal conditions. In the structure, the oxalate and 5-amino-isophthalate ligands link the dysprosium ions, building up a two-dimensional metal-organic framework parallel to the (10) plane. These sheets are further connected through O-H⋯O, N-H⋯O and C-H...

The title dysprosium coordination polymer, {[Dy(2)(C(10)H(8)O(6))(3)(H(2)O)(2)]·2H(2)O}(n), was synthesized by reacting dysprosium(III) nitrate and the flexible ligand (p-phenyl-enedi-oxy)diacetic acid under hydro-thermal conditions. Each Dy(III) ion is coordinated by nine O atoms in a tricapped trigonal prismatic geometry. The DyO(9) polyhedra form layers parallel to the bc plane. The rigid be...

Crystals of the title dysprosium tin sulfide oxide, Dy(8)SnS(13)S(1-x)O(x) [x = 0.39 (4)], were obtained unintentionally from the Dy-Sn-S system. A statistical mixture of sulfur and oxygen was assumed for one position in the structure. S and O atoms surround each of the eight symmetrically non-equivalent dysprosium atoms. The Sn atoms are located in tetra-hedral surroundings of sulfur atoms. Tr...

Radio-frequency electric-dipole transitions between nearly degenerate, opposite parity levels of atomic dysprosium (Dy) were monitored over an eight-month period to search for a variation in the fine-structure constant, α. The data provide a rate of fractional temporal variation of α of (−2.4±2.3)×10 −15 yr −1 or a value of (−7.8 ± 5.9) × 10 −6 for kα, the variation coefficient for α in a chang...

Graphene based spintronic devices require an understanding of the growth of magnetic metals. Rare earth metals have large bulk magnetic moments so they are good candidates for such applications, and it is important to identify their growth mode. Dysprosium was deposited on epitaxial graphene, prepared by thermally annealing 6H-SiC(0001). The majority of the grown islands have triangular instead...
