Vortex Response, Dimensionality and Fluctuations in High-Tc Oxide Superconductors
Abstract
This final report encompasses the following research results: In-situ reactive sputter deposition of nanometer-smooth superconducting BSCCO thin films; New method of ozone detection for use with reactive thin-film growth; Fabrication of and detailed noise properties of thin-film dc BSCCO SQUIDs; Power-law scaling of the longitudinal and transverse Hall resistivities due to vortex motion in YBCO, with implications for the nature of the vortex state; Measurement of the ac screening response of 2212 BSCCO crystals, and interpretation within electromagnetic skin depth effects; Vortex flux creep and high-magnetic-field critical currents of epitaxial YBCO thin films.
