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.
