This paper reviews recent progress on metal-rich -carbide-type compounds as bulk superconductors, highlighting how their crystal symmetry, composition, and electronic structure enable high-field superconductivity that notably violates the weak-coupling Pauli limit.
This paper demonstrates that NbN-insulator-ferromagnet tunnel junctions, fabricated using a simple two-step process with an oxidized barrier, effectively enable reliable Meservey-Tedrow spin-polarization measurements of ferromagnets at 4He temperatures by exhibiting clear Zeeman splitting in the superconducting density of states for films thinner than 10 nm.
This study utilizes x-ray absorption spectroscopy to demonstrate that a Ni-O orbital-selective crossover, characterized by a redistribution of spectral weight from Ni 3d to O 2p states near optimal doping, drives transport anomalies and governs the superconducting dome in infinite-layer LaCaNiO.
By mapping the complete superconducting dome of electron-doped FeSe, this study reveals that the transition temperature scales robustly with residual resistivity across the entire doping range, indicating that the superconducting dome is primarily driven by disorder sensitivity rather than doping levels, distinguishing it from other unconventional superconductors.
This paper proposes that the unconventional superconductivity observed on the surface of the Weyl semimetal PtBi arises from a Kohn-Luttinger mechanism mediated by repulsive interactions on Weyl Fermi arcs, which robustly leads to a topological -wave pairing state featuring a node at the center of each arc.
This paper explores the potential of ceramic superconductors to advance United Nations Development Goals through bibliometric analysis and by highlighting their diverse applications in sustainable energy, healthcare, transportation, environmental protection, and quantum computing, while acknowledging the remaining challenges in fully integrating these technologies with global development objectives.
This study demonstrates that quantum anharmonic effects stabilize a previously unknown, vacancy-free cubic phase of stoichiometric NbN with a superconducting transition temperature of 20 K, challenging the long-held belief that vacancies are essential for its structural stability.
This paper reports the discovery of high-field-stabilized reentrant superconductivity in infinite-layer nickelate thin films with transition temperatures up to 40 K, where both low- and high-field superconducting states are attributed to a Jaccarino-Peter-like compensation mechanism that significantly enhances the upper critical field.
Using resonant inelastic X-ray scattering on Nd2-xCexCuO4, this study reveals a continuous evolution of collective charge excitations from acoustic plasmons to a gapped hybrid mode and finally to a 139 meV excitation at half-filling, demonstrating that strong coupling to lattice degrees of freedom unifies the charge dynamics across the Mott transition in electron-doped cuprates.
This paper reports the first observation of hole-doped superconductivity in infinite-layer SrRbCuO thin films with an onset temperature above 100 K, achieved through a synergistic mechanism of rubidium substitution and apical oxygen incorporation.
