Abstract

The spatial distribution of the resistive transition for laser deposited c-axis oriented epitaxial YBa₂Cu₃O₇-films on &:#60;100> SrTiO₃ has been imaged by low temperature scanning electron microscopy (LTSEM) with a spatial resolution of about 1 μm. The films which have critical current densities up to 5 × 10⁶ A/cm² at 77 K show temperature variations in the local resistive transition curves up to 200 mK. Possible reasons for the observed inhomogeneous behavior are discussed.
