Abstract:We investigate the low-frequency electrodynamics in the vortex state of two type-II superconducting films, namely, a moderate-to-strongly pinned Niobium Nitride (NbN) and a very weakly pinned amorphous Molybdenum Germanium (a-MoGe). We employ a two-coil mutual inductance technique to extract the complex penetration depth, λ ̃. The sample response is studied through the temperature variation of λ ̃ in the mixed state, where we employ a model developed by Coffey and Clem (CC model) to extract the different vorte… Show more
