Local and long-range realizations of a spin-reorientation surface phase transition
G. He, H. Winch, R. Belanger +2
The spin reorientation transition of an ultrathin film from perpendicular to in-plane magnetization is driven by a competition between dipole and anisotropy energies. \textit{In si…
A conducting nano-filament (CNF) network as a precursor to the origin of superconductivity in electron-doped copper oxides
Heshan Yu, Ge He, Ziquan Lin +9
Emergency of superconductivity at the instabilities of antiferromagnetism has been widely recognized in unconventional superconductors. In copper-oxide superconductors, spin fluctu…
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…
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…
