Effect of Co Impurities on Superconductivity of FeSe0.4Te0.6 single crystals
Fuyuki Nabeshima, Yusuke Kobayashi, Yoshinori Imai +2
The effect of Co doping on supercoductivity of FeSeTe single crystals is investigated. The superconducting transition temperature decreases linearly for Co doping w…
Superconducting Fluctuation investigated by THz Conductivity of LaSrCuO Thin Films
Daisuke Nakamura, Yoshinori Imai, Atsutaka Maeda +1
Frequency-dependent terahertz conductivities of LaSrCuO thin films with various carrier concentrations were investigated. The imaginary part of the complex conducti…
Anomalous Temperature Dependence of the Superfluid Density Caused by Dirty-to-Clean Crossover in FeSeTe Single Crystals
Hideyuki Takahashi, Yoshinori Imai, Seiki Komiya +2
We report microwave surface impedances of FeSeTe single crystals measured at 12, 19, and 44 GHz. The penetration depth exhibits a power law behavior, $δλ_L=λ_L (T)-…
Breakdown of the universal Josephson relation in spin ordered cuprate superconductors
A. A. Schafgans, C. C. Homes, G. D. Gu +3
We present \emph{c} axis infrared optical data on a number of Ba, Sr and Nd-doped cuprates of the LaCuO (La214) series in which we observe significant deviations from t…
Epitaxial growth of FeSeTe thin films on CaF substrates with high critical current density
I. Tsukada, M. Hanawa, T. Akiike +8
In-situ epitaxial growth of FeSeTe thin films is demonstrated on a non-oxide substrate CaF. Structural analysis reveals that compressive stress is moderately ad…
Hall effect of FeTe and Fe(Se_1-x_Te_x_) thin films
I. Tsukada, M. Hanawa, Seiki komiya +4
The Hall effect is investigated in thin-film samples of iron-chalcogenide superconductors in detail. The Hall coefficient (RH) of FeTe and Fe(Se1-xTex) exhibits a similar positive…
An extended infrared study of the (p,T) phase diagram of the p-doped Cu-O plane
D. Nicoletti, P. Di Pietro, O. Limaj +5
The ab-plane optical conductivity of eleven single crystals, belonging to the families Sr2-xCuO2Cl2, Y1-xCaxBa2Cu3O6, Bi2Sr2-xLaxCuO6, and Bi2Sr2CaCu2O8 has been measured with hole…
