Correlation between superfluid density and transition temperature in infinite-layer nickelate superconductor
Z. J. Li, R . Z. Zhang, M. H. Xu +10
A strong correlation between zero-temperature superfluid density () and transition temperature () is considered as a hallmark of unconventional superconductivity. Howe…
Correlation between unconventional superconductivity and strange metallicity revealed by operando superfluid density measurements
Ruozhou Zhang, Mingyang Qin, Chenyuan Li +15
Strange-metal behavior has been observed in superconductors ranging from cuprates to pressurized nickelates, but its relationship to unconventional superconductivity remains elusiv…
Enhancement of Superconductivity Linked with Linear-in-Temperature/Field Resistivity in Ion-Gated FeSe Films
Xingyu Jiang, Mingyang Qin, Xinjian Wei +25
Iron selenide (FeSe) - the structurally simplest iron-based superconductor, has attracted tremendous interest in the past years. While the transition temperature (Tc) of bulk FeSe…
Determining the absolute value of magnetic penetration depth in small-sized superconducting films
Ruozhou Zhang, Mingyang Qin, Lu Zhang +6
In the previous four decades, a two-coil mutual inductance (MI) technique has been widely employed in characterizing magnetic penetration depth, , of superconducting films. Howe…
