Yttrium Superhydrides Revisited: Advanced Experimental and Theoretical Studies of YH, YH and YH
Dmitrii V. Semenok, Pedro N. Ferreira, Di Zhou +10
Yttrium polyhydrides are benchmark materials in high-pressure superconductivity, yet several key properties of the Y-H system remain insufficiently characterized. Here we combine c…
Radio-Frequency Method for Detecting Superconductivity Under High Pressure
Dmitrii V. Semenok, Di Zhou, Jianbo Zhang +5
We introduce a contactless technique for probing superconductivity and magnetic ordering transitions in micron-sized samples under extreme pressure. Utilizing a multistage Lenz len…
Superhydrides on the way to ambient pressure: weak localization and persistent X-ray photoconductivity in BaSiH
Dmitrii V. Semenok, Di Zhou, Sven Luther +15
Reducing the stabilization pressure of superhydrides represents one of the most important challenges in hydrogen-saturated compound chemistry. Moving in this direction, we studied…
Hall effect on nontrivial quadrupole order in quasi-kagome compound URhSn
Yusei Shimizu, Arvind Maurya, Yoshiya Homma +6
This study focuses on the transport properties of the quasi-kagome compound URhSn, which exhibits successive phase transitions at TC =16 K (ferromagnetic phase) and TO =54 K (inter…
Stability and Superconductivity of Ternary Polyhydrides
Dmitrii V. Semenok, Di Zhou, Wuhao Chen +8
We review five years of experimental and theoretical attempts (2020-2025) to enhance the superconducting critical temperature ($\textit{T$_c$}$) of hydrogen-rich compounds by alloy…
Soft superconductivity in covalent bismuth dihydride BiH under extreme conditions
Jianning Guo, Dmitrii V. Semenok, Ivan A. Troyan +14
Strong magnetic fields provide a unique environment for investigating the fundamental properties of superconducting materials, especially for hydride superconductors with large upp…
