Impact of Ge Doping on Structural and Magnetic Ordering in RMnGa and RMnGaGe (R = Tb, Dy; ≤ 0.25, ≈ 1.0-3.3).

Single crystals of RMnGa and their new quaternary derivatives RMnGaGe (R = Tb, Dy, ≤ 0.25, ≈ 1.0-3.

Fine details of crystal structure and atomic vibrations in YbB with a metal-insulator transition.

The crystal structure of single-crystal Kondo insulator YbB was studied at nine temperatures in the range 85-293 K based on X-ray diffraction data. Very weak Jahn-Teller distortions of the cubic lattice were detected at all temperatures, but did not require a revision of the structural model. Heat capacity and electrical conductivity of YbB single crystals were studied in the temperature range 1.

Tennantite: multi-temperature crystal structure, phase transition and electronic structure of synthetic CuAsS.

The structure of synthetic tennantite CuAsS was investigated at various temperatures in the 90-293 K range. It crystallizes in space group I{\overline 4}3m. No structural transformation was observed in this temperature range.

The lower symmetry electron-density distribution and the charge transport anisotropy in cubic dodecaboride LuB.

High-quality single crystals of LuB are grown using the induction zone melting method. The x-ray data are collected at temperatures 293, 135, 95, 50 K. The crystal structure of LuB can be refined with record low R-factor in the cubic Fm [Formula: see text] m symmetry group despite reiterated observations of the cubic symmetry distortions both in the unit-cell values and in the physical properties.
