Essay

The object is the phenomenons and mechanisms what they defining the transition from superconducting to dissipa- tive states and nonlinear conductivity in inhomogeneous (granulating) type II superconductors. The aim was to investigated of the dissipation of energy and to defined the character of the resistance. Method is devices for con- ducting and current measurements. Results, novelty - revealed is existence of phase slipping bands, it is found that the transition into dissipative state is caused by penetration of vortices shaped as rings or helixes Josephson's, found are quantized Abrikosov's vorticesbroken at inhomogeneities and the value of paraconductivity depends on the quantity of mobile charge carriers (holes). Employment - fundamental science, prepare superconducting conductors.
