Abstract :
The experimental results of the film parameter evaluation based on recording detective coil signal produced by the film in external or remanent magnetic field subject to a laser pulse at any specific spot in the film are presented. The mechanisms of the film response to the laser irradiation based on Bean-like model for the inhomogeneous superconductive film are discussed.<>
