Sažetak
Temperature and magnetic field dependent measurements of the microwave surface impedance in the novel superconductor LaO_0.9F_0.1FeAs reveal a very large upper critical field (\Bc2~$\approx 56$T) and a large value of the depinning frequency (f_0 \approx 6GHz) together with the measured effective penetration depth, \lambda_eff=200 \pm 50$nm, our results indicate a stark similarity between this system and the high-T_c superconducting cuprates.
