Autor: Bolotina, Nadezhda B., Dudka, Alexander P., Khrykina, Olga N., Mironov, Vladimir S.

Publikováno v: Jenny Stanford Publishing (2021), ISBN 978-9814877565

Analysis of the intriguing physical properties of the dodecaborides, $R$B$_{12}$, requires accurate data on their crystal structure. We show that a simple cubic model fits well with the atomic positions in the unit cell but cannot explain the observe

Report

Quantum diffusion regime of the charge transport in GdB6 caused by electron and lattice instability

Autor: Dudka, Alexander P., Khrykina, Olga N., Bolotina, Nadezhda B., Shitsevalova, Natalya Yu., Filipov, Volodymyr B., Anisimov, Mikhail A., Gabani, Slavomir, Flachbart, Karol, Sluchanko, Nikolay E.

Publikováno v: Phys. Rev. B 100, 205103 (2019)

Based on accurate X-ray structure analysis of GdB6 over the temperature range 85-300 K it has been shown that anomalously strong charge carrier scattering in the quantum diffusion regime of charge transport in this compound arises due to the formatio

Report

Thermal and charge transport characteristics and fine details of the crystal structure in dodecaborides LuNB12 (N = 10, 11, nat) with the Jahn-Teller instability

Autor: Bolotina, Nadezhda B., Dudka, Alexander P., Khrykina, Olga N., Glushkov, Vladimir V., Azarevich, Andrey N., Krasnorussky, Vladimir N., Gabani, Slavomir, Shitsevalova, Natalya Yu., Dukhnenko, A. V., Filipov, Volodymyr B., Sluchanko, Nikolay E.

Structure differences of isotopically different dodecaborides LuNB12 (N = 10, 11, natural) and their impact on thermal and charge transport characteristics of the crystals have been first discovered. Atomic displacement parameters (ADPs) of Lu and B

Report

The lower symmetry electron-density distribution and the charge transport anisotropy in cubic dodecaboride LuB12

Autor: Bolotina, Nadezhda B., Dudka, Alexander P., Khrykina, Olga N., Krasnorussky, Vladimir N., Shitsevalova, Natalya Yu., Filipov, Volodymyr B., Sluchanko, Nikolay E.

High-quality single crystals of LuB12 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 LuB12 can be refined with record low R-factor in the cubic Fm-3m symmet
