N2 - Thin films of La0.67Sr0.33MnO3 and La 0.7Sr0.3MnO3 were prepared by different sputtering techniques. All films show a significant magnetoresistive effect. The topographic and electronic properties of the films were studied by STM/STS under ambient conditions. The local conductance of different films and of spatially separated areas on a film was measured. A surprisingly high degree of homogeneity was found in contrast to previous comparable experiments.
