Abstract

"We study the dynamics of vortex lines in Supercondutor\/Ferromagnet\/Superconductor (SFS) heterostruc-. tures at microwave frequencies. We have employed swept-frequency, Corbino-disk and resonant, dielec-. tric-resonator techniques to obtain the field and temperature dependence of the vortex-state parameters.. We concentrate here on the genuine flux-flow resistivity qff, that we access at subcritical currents using a. sufficiently high driving frequency. We find that qff does not follow the well-known Bardeen–Stephen. model. Instead, it is well described by a full time-dependent Ginzburg–Landau expression at very thin. F layer thickness, but changes to a previously unreported field-dependence when the F layer exceeds a. few nm.. "
