Pauli-limited upper critical field and anisotropic depairing effect of La2.82Sr0.18Ni2O7 superconducting thin film
Ke Wang, Maosen Wang, Wei Wei +10
We investigate the upper critical field and superconducting anisotropy of epitaxial La2.82Sr0.18Ni2O7 thin films, which show a sharp superconducting transition at Tc=31.6 K. Near T…
Increase of critical current density in FeSe superconductor by strain effect
Han Luo, Xinyue Wang, Xin Zhou +6
Conventional -enhancement methods like doping and irradiation often introduce extrinsic elements or defects, altering intrinsic properties. Here, we report a significant …
Depairing critical current density and the vortex-free state in FeSe nanobridges
Yue Sun, Yuling Xiang, Zhixiang Shi +1
The depairing limit and the vortex-free state in a superconductor is crucial for both the study of supercurrent related physics and the application eliminating noise linked to vort…
Impact of Disorder on the Superconducting Properties and BCS-BEC Crossover in FeSe Single Crystals
Jianping Fu, Yue Sun, Jingting Chen +2
We investigate the crystal structure, transport properties and specific heat in five selected FeSe single crystals containing different amounts of disorder. Transport measurements…
Upper critical fields in high- superconductors
Wei Wei, Yuling Xiang, Qiang Hou +2
Since the discovery of high-temperature superconductivity in cuprates, understanding the unconventional pairing mechanism has remained one of the most significant challenges. The u…
Strong correlation between -linear magnetoresistance and strange metal in FeSe superconductor
Xinyue Wang, Yue Sun, Wei Wei +4
In strange metals, a strong and anomalous scattering effect exists and increases linearly with temperature. In FeSe, we observed that the temperature dependence of resistivity exhi…
