Direct Observation of Phase Oscillation Modes in Josephson-coupled Layered Superconductors

Z. Y. Lai, X. Yao, X. H. Zeng +4

We have proposed to employ the microwave S parameters method to measure phase oscillation modes (POMs) in Josephson coupled-layered superconductors. For the first time, in SmBa2Cu3…

Hole Doping Dependence of the Coherence Length in $L a_{2 - x} S r_{x} C u O_{4}$ Thin Films

H. H. Wen, H. P. Yang, S. L. Li +4

By measuring the field and temperature dependence of magnetization on systematically doped $L a_{2 - x} S r_{x} C u O_{4}$ thin films, the critical current density $j_{c} (0)$ and the collective…

Critical Current Density and Resistivity of MgB2 Films

J. M. Rowell, S. Y. Xu, X. H. Zeng +6

The high resistivity of many bulk and film samples of MgB2 is most readily explained by the suggestion that only a fraction of the cross-sectional area of the samples is effectivel…

The superconducting gap of \QTR{em}{in situ} $M g B_{2}$ thin films by microwave surface impedance measurements

N. Hakim, C. Kusko, S. Sridhar +4

Precision measurements of the microwave surface resistance $R_{s}$ of in situ $M g B_{2}$ films directly reveal an exponential behavior of $R_{s}$ at low temperature indicating a ful…
