dc.description.abstract	Magnetization and sup(75)As nuclear magnetic resonance (NMR) measurements in the superconductor NdFeAsO sub(0.83)F sub(0.17) (T sub(C) approx 46 K) are performed in order to investigate the effect of the Nd 4f electrons in the superconducting property. The magnetization curve displays a Nd 4f moments generated Curie-Weiss signal in the field of 7 T. sup(75)As NMR spectra in the oriented sample (H sub(0)	en_US

The K sub(ab) curve shows a Curie-Weiss type contribution. The magnitude of hyperfine field, H hf (4.4 kOe/mu sub(B)) estimated from the K sub(ab) vs X plot indicates a non-negligible RKKY-type interaction between localized Nd 4f moments mediated by itinerant Fe 3d electrons.	en_US
