Abstract: Flux Manipulation at High Frequencies in Nano- and Mesoscopic High-Tc Thin FilmsRoger Wördenweber, Eugen Hollmann, Jürgen Schubert, Gregor Panaitov, Stefan Trellenkamp Peter Grünberg Institute (PGI) and JARA-Fundamentals of Future Information Technology, Forschungszentrum Jülich, D-52425 Jülich, GermanyVortex matter represents an extremely colorful physics including among others flux pinning (important for a number of technical applications, e.g. coated conductors) and flux manipulation (important for a number of electronic applications). Obviously, it was always and still is desirable to use artificially created pinning sites to either improve flux pinning or stimulate flux motion according to the requirements of the specific application. In this presentation, we will focus on the impact of arrays of holes (antidots) in thin superconducting films on flux pinning and flux manipulation. First different aspects of the arrangement, shape and size of the holes are summarized. Then experimental results of dc, ac, to microwave manipulation of flux in nano- and mesoscopic patterned structures ranging from HTS nanobridges, extended arrays of HTS antidot lattices to novel flux guiding structures will be presented. The data are discussed in the framework of their potential for fluxonic devices.
