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…
Effect of paramagnetic impurities on superconductivity in polyhydrides: -wave order parameter in Nd-doped LaH
Dmitrii V. Semenok, Ivan A. Troyan, Andrey V. Sadakov +19
Polyhydrides are a novel class of superconducting materials with extremely high critical parameters, which is very promising for applications. On the other hand, complete experimen…
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…
Spin-glass behavior in single crystals of hetero-metallic magnetic warwickites , , and
Ana Arauzo, Natalya V. Kazak, Natalya B. Ivanova +8
Magnetic properties of heterometallic warwickites , , and are presented, highlighting the effect of Co substitution on the magnetic pro…
Quantum critical point and spin fluctuations in the lower-mantle ferropericlase
I. S. Lyubutin, V. V. Struzhkin, A. A. Mironovich +7
Ferropericlase, (Mg,Fe)O is one of the most abundant minerals of the Earth's lower mantle. The high-spin (HS) to low-spin (LS) transition in the Fe2+ ions can dramatically alter th…
