چکیده انگلیسی
The stationary thermal state of a long superconducting film on a wide substrate is analyzed analytically. Expressions describing voltage-current characteristics and temperature-current dependence of the film are derived for the flux creep, flux flow and normal regimes. It is shown how the flux creep influences the conditions of the thermal stability. In particular, it is found that the bistability of the thermal state can appear in this regime. Under the boiling crisis, the temperature-current dependence for a film differs markedly from that for a wire and is characterized by a smooth temperature increase with the current. A “mixed” regime is analyzed where the flux flow and normal states exist simultaneously with the boundary between them parallel to the film axis.
