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…
Anomalous and Topological Hall Effects in Antiferromagnetic EuSn2As2 Nanostructures
Evgeny I. Maltsev, Nicolas Pérez, Romain Giraud +8
We investigate magnetotransport in exfoliated nanostructures of the candidate magnetic 3D topological insulator . Similar to macroscopic single crystals, t…
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…
Ferromagnetic resonance in an antiferromagnetic crystal EuSnAs
I. I. Gimazov, D. E. Zhelezniakova, R. B. Zaripov +7
We report results of electron spin resonance (ESR) measurements in single crystals of EuSnAs. In the temperature range of antiferromagnetic (AFM) ordering of Eu atoms, $T \…
Universal negative magnetoresistance in antiferromagnetic metals caused by symmetry breaking of electron wave functions
Pavel D. Grigoriev, Nikita S. Pavlov, Igor A. Nekrasov +5
Layered van der Waals crystals of topologically non-trivial and trivial semimetals with antiferromagnetic (AFM) ordering of magnetic sublattice are known to exhibit a negative magn…
Stability and Superconductivity of Ternary Polyhydrides
Dmitrii V. Semenok, Di Zhou, Wuhao Chen +8
We review five years of experimental and theoretical attempts (2020-2025) to enhance the superconducting critical temperature ($\textit{T$_c$}$) of hydrogen-rich compounds by alloy…
