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…
Stability Analysis of Superconductivity in -LaScH and its Experimental Reproducibility from La-Sc Alloys
Dmitrii V. Semenok, Ivan A. Troyan, Di Zhou +4
In this work, we analyze the feasibility of room-temperature superconductivity in the lanthanum-scandium hydride -LaScH. We demonstrate that the electro…
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…
Radio-Frequency Gasket for Studies of Superconductivity in Diamond Anvil Cells
Dmitrii V. Semenok, Di Zhou, Viktor V. Struzhkin
This work presents the development and testing of a novel radio-frequency (RF) gasket with a Lenz lens surface geometry for contactless measurements in diamond anvil cells (DACs).…
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…
Interlayer coupling enhanced superconductivity near 100 K in LaNdNiO
Zhengyang Qiu, Junfeng Chen, Dmitrii V. Semenok +12
Systematically controlling the superconducting transition temperature () in the bilayer Ruddlesden-Popper nickelate LaNiO remains a significant challenge. H…
