superconducting transition temperaturethulium compoundsvalencyGaSr 2 Tm 1 x Ca x Cu 2 O 7 was prepared at 2 GPa. Energy dispersive X-ray (EDX) analysis reveals the formation of two kinds of Ga-1212 phases, GaSr 2 (Tm,Sr,Ca)Cu 2 O 7 and Ga(Sr,Ca) 2 (Tm,Ca)Cu 2 O 7 , in ...
In weak coupling, the ratio of the transition temperature to the spin-zero gap at zero temperature is the same as in BCS theory. We classify the gaps with spin one, and find that they are of the same order in g as the spin-zero gap....
Stabilized FeSe thin films in ambient pressure with tunable superconducting critical temperature would be a promising candidate for superconducting electronic devices. By carefully controlling the depositions on twelve kinds of substrates using a pulsed laser deposition technique single crystalline FeSe thin ...

understanding the relationship between superconductivity and materials’ chemistry and structure presents significant theoretical and experimental challenges. In particular, despite focused research efforts in the last 30 years, the mechanisms responsible for high-temperature superconductivity in cuprate and iron-...
