摘要：

We have observed flux-flow resistivity in superconducting sintered polycrystalline Y123 over the temperature range of 5-89 K, using a contact-less microwave technique, in an applied magnetic field varying to a maximum of 1.9 T. Flux-flow is observed superimposed on an isotropic background resistivity, and is at maximum several degrees below the transition temperature. Flux-flow resistivity, a consequence of the Lorentz force on a fluxoid, varies as sin2(phi), where phi is the angle between the applied magnetic field and the RF current.
