Engineering Physics Annotation << Back Experimental research of electrodynamic properties of "three-dimensional" composites cunb with extremely fine structure I.F. Voloshin, P.N. Degtyarenko, A.S. Ivanov, V.S. Kruglov Electrodynamics properties of "three-dimensional" composites CuNb with extremely fine structure and different concentration of components are investigated. The samples have been fabricated from the melt using slow and extremely fast cooling rate. On the basis of the experimental data we have estimated a coherence length of the effective superconducting media. Voltage–current characteristics of the quenched sample in magnetic fields parallel and perpendicular to the current show abnormally low slope in some intermediate current region.
