Temperature-dependent and magnetic-field-dependent measurements of the microwave surface impedance of superconducting LaFeAsO(0.9)F(0.1) (T(c)approximate to 26 K) reveal a very large upper critical field (B(c2)approximate to 56 T) and a large value of the depinning frequency (f(0)approximate to 6 GHz); to
