Non-Fermi-Liquid Behavior of Superconducting SnH
Ivan A. Troyan, Dmitrii V. Semenok, Anna G. Ivanova +13
We studied chemical interaction of Sn with H by X-ray diffraction methods at pressures of 180-210 GPa. A previously unknown tetrahydride SnH with a cubic structure (…
High-temperature superconductivity in hydrides
I. A. Troyan, D. V. Semenok, A. G. Ivanova +7
Over the past six years (2015-2021), many superconducting hydrides with critical temperatures up to 250 K, which are currently record highs, have been discovered. Now we ca…
Novel Strongly Correlated Europium Superhydrides
Dmitrii V. Semenok, Di Zhou, Alexander G. Kvashnin +11
We conducted a joint experimental-theoretical investigation of the high-pressure chemistry of europium polyhydrides at pressures of 86-130 GPa. We discovered several novel magnetic…
Superconductivity at 253 K in lanthanum-yttrium ternary hydrides
Dmitrii V. Semenok, Ivan A. Troyan, Alexander G. Kvashnin +14
Polyhydrides offer intriguing perspectives as high-temperature superconductors. Here we report the high-pressure synthesis of a series of lanthanum-yttrium ternary hydrides: cubic…
Crystal structure and phase transitions at high pressures in the superconductor FeSe0.89S0.11
Yulia A. Nikiforova, Anna G. Ivanova, Kirill V. Frolov +8
We report on the structural phase transitions in the S doped FeSe superconductor by powder synchrotron X ray diffraction at high pressures up to 18.5 GPa under compression and deco…
Anomalous high-temperature superconductivity in YH
Ivan A. Troyan, Dmitrii V. Semenok, Alexander G. Kvashnin +16
Pressure-stabilized hydrides are a new rapidly growing class of high-temperature superconductors which is believed to be described within the conventional phonon-mediated mechanism…
Superconductivity and Equation of State of Distorted fcc-Lanthanum above Megabar Pressures
Wuhao Chen, Dmitrii V. Semenok, Ivan A. Troyan +4
Lanthanum (La) is the first member of the rare-earth series of elements that has recently raised considerable interest because of its unique high-Tc superhydride LaH10. Although se…
Superconductivity at 161 K in Thorium Hydride : Synthesis and Properties
Dmitrii V. Semenok, Alexander G. Kvashnin, Anna G. Ivanova +7
Here we report targeted high-pressure synthesis of two novel high- hydride superconductors, - and -, with the experimental critical temp…
