Dislocations and superconductivity in metallic monospirals at the room and positive temperatures

Abstract

The description of experimentally observed phenomenon of abnormally high electrical conductivity-“superconductivity” (SC) at the room and higher temperatures is represented. The effect was observed in metallic monospirals of small radius curvature with high density and regular distribution of dislocations. Transition into state of SC has been observed experimentally in the range from -50°C up to 3000°C at the density of transmitting current up to 2 × 109 A cm-2. The experimental data confirming the watched phenomenon are represented. The explanations of this phenomenon are being proposed in the framework of the dislocation model.
