Crystallographic dependent transport properties and oxygen issue in superconducting LiTi2O4 thin films
Yanli Jia, Ge He, Heshan Yu +10
A systematic study is performed on the spinel oxide, i.e. LiTi2O4 thin films oriented along [111]-, [110]-, and [001]-directions, to reveal the crystallographic dependence of trans…
Anisotropic electron-phonon coupling in the spinel oxide superconductor
Ge He, Yanli Jia, Xingyuan Hou +12
Among hundreds of spinel oxides, LiTi2O4 (LTO) is the only one that exhibits superconductivity (Tc ~13 K). Although the general electron-phonon coupling is still the main mechanism…
Observation of Ising spin-nematic order and its close relationship to the superconductivity in FeSe single crystals
Yuan Dongna, Yuan Jie, Huang Yulong +9
Superconducting FeSe single crystals of (001) orientation are synthesized via a hydrothermal ion-release route. An Ising spin-nematic order is identified by our systematic measurem…
Transport anomalies and quantum criticality in electron-doped cuprate superconductors
Xu Zhang, Heshan Yu, Ge He +4
Superconductivity research is like running a marathon. Three decades after the discovery of high-Tc cuprates, there have been mass data generated from transport measurements, which…
