The doping dependence of superconductivity of (Ca1-xNax)Fe2As2
K. Zhao, Q. Q. Liu, X. C. Wang +5
Single crystalline CaFe2As2 and (Ca1-xNax)Fe2As2 polycrystals (0 < x < 0.66) are synthesized and characterized using structural, magnetic, electronic transport, and heat capacity m…

Out of plane effect on the superconductivity of Sr2-xBaxCuO3+y with Tc up to 98K
W. B. Gao, Q. Q. Liu, L. X. Yang +4
A series of new Sr2-xBaxCuO3+y (0 x 0.6) superconductors were prepared using high-pressure and high-temperature synthesis. A Rietveld refinement based on powder x-ray diffraction c…
