Abstract
The electrical resistance of a superconducting BSCCO (2212) film is ex amined as a function of temperature, electric current and magnetic fie ld. The large temperature dependence and the existence of current and magnetic field independent regions suggest a thermal origin of the flu xons. The analysis of the R(T) dependence, in agreement with the Koste rlitz-Thouless theory, supports this hypothesis.
