Microwave study of magnetic field penetration parallel to thin niobium films
Complex conductivity of high quality niobium thin films has been investigated by microwave technique in parallel static magnetic field. For the 40 nm thick film no vortices can be formed and microwave penetration is defined by strength of superconducting order parameter which varies with applied magnetic field. 160 nm thick measured film allows formation of two rows of vortices. Microwave disipation is dominated by dynamics of vortices which is strongly affected by size effects. Results have been compared with generalised models of complex conductivity for low - dimensional superconductor in mixed state following earlier considerations by other authors.
