Ferromagnetism was found to coexist with superconductivity in Dy-doped BiPbSrCaCuO-2212 single crystals up to the superconducting critical temperature T-c similar to 80 X. Several experimental tests indicated that the phenomenon is intrinsic to the entire ...
We present the resistivity measurements on single crystals of Sr2RuO4-delta, grown by the flux technique. We discuss the striking, linear temperature dependence of resistivity that persists up to similar to 1050 K. The superconductivity in this system is c ...
Thirteen years ago, late in 1986, several groups confirmed striking claims of the famous paper by Bednorz and Muller [see Z Phys. B, vol.64, p.189 (1986)] that announced the discovery of high-Tc superconductivity in cuprates. Some 60000 papers later, we ar ...
We present an experimental study of the current induced destruction of superconductivity in films of type-1 superconductors. The most interesting aspect of these experiments is the possibility to observe and investigate different mechanisms of the supercon ...
Low-frequency dynamic impedance [σ−1(ω,T)≡(σ1+iσ2)−1] measurements on Josephson junction arrays found that σ1∼|lnω|, σ2∼const. This implies anomalously sluggish vortex mobilities μV(ω)∼σ−11, and is in conflict with general dynamical scaling expressions. We ...
Recent photoemission evidence for non-zero gap in highly overdoped Bi2Sr2-CaCu2O8+x, along the directions in the Brillouin zone where the d-wave gap exhibits nodes, is in accordance with more conventional behavior in strongly overdoped high-T-c cuprates. T ...
