We report the high temperature behaviour of single-phase YBa2Cu3O9 − y. This compound reveals superconductivity above 90 K. We performed high temperature (20–960 °C) resistivity measurements, differential thermal analysis and thermogravimetric a

Bulk single crystals of the ternary intermetallic compounds UT 2 Si 2 (T = Ni, Pd, Pt and Ru), LaT 2 Si 2 (T = Pd and Rh) and LuPd 2 Si 2 have been grown from the melt with a modified “tri-arc” Czochralski method. The as-grown crystals were chara

We describe our observations on the unusual formation and morphology of whiskers of the intermetallic uranium compound UPt3 (MgCd3 hexagonal-type of structure). Needle-like whiskers of this compound grow spontaneously from the stoichiometric UPt3 mel

Thermal and constitutional vacancies are studied for five compositions of the intermetallic compound CoGa. Macroscopic density measurements are used to determine the structural and frozen-in thermal vacancy content. The formation of thermal vacancies

The results of neutron and X-ray diffraction experiments at 300 and 4.2 K on the intermetallic compound TmNi 2 indicate that the crystal structure of the two modifications of TmNi 2 observed by us are closely related to the cubic Laves phase structur

Thermal expansion, longitudinal magnetostriction and magnetization under high pressures of YbCuAl are presented. All results are in complete accordance with what is expected for a compound containing Yb in the mixed-valent state.

Due to the presence of magnetic impurities in compounds containing intermediate valent Ce there is much confusion about the intrinsic susceptibility at low temperatures. In this paper high-field magnetization and suceptibility measurements are presen
