Microwave properties of Nb/PdNi/Nb trilayers. Observation of flux flow in excess of Bardeen-Stephen theory
Abstract
We combine wideband (1-20 GHz) Corbino disk and dielectric resonator (8.2 GHz) techniques to study the microwave properties in Nb/PdNi/Nb trilayers, grown by UHV dc magnetron sputtering, composed by Nb layers of nominal thickness dS=15 nm, and a ferromagnetic PdNi layer of thickness dF= 1, 2, 8 and 9 nm. We focus on the vortex state. Magnetic fields up to Hc2 were applied. The microwave resistivity at fixed H/Hc2 increases with dF, eventually exceeding the Bardeen Stephen flux flow value.
