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…
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…
Vortex matter and strong pinning in underdoped PrFeAs(O,F) with atomic-sized defects
Andrey V. Sadakov, Vladimir A. Vlasenko, A. Yu. Levakhova +6
We present a comprehensive investigation of the field-dependent critical current density and pinning force, combined with a detailed analysis of the nanostructural defect landscape…
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…
Strong negative magnetoresistance and hopping transport in graphenized nematic aerogels
V. I. Tsebro, E. G. Nikolaev, M. S. Kutuzov +2
The transport properties of nematic aerogels, which consist of oriented mullite nanofibers coated with a graphene shell, were studied. It is shown that the magnetoresistance of thi…
