Abstract A method (laser raster microscopy with thermal excitation, LRMTE) for characterizing high-T c thin-film superconductors (HTSC) with microscopic resolution is described. By means of spatially resolved laser excitation and subsequent monitoring of the time dependence of the film resistivity at a base temperature near the transition temperature T c, spatial variations of the transition temperature (T c), of the temperature coefficient of the resistivity (dQ/dT), of the heat conductivity and heat capacity of the film and of the heat conductivity between film and substrate can be detected with high spatial resolution (15 μm have been achieved so far).
