We have studied the structural, magnetic, and transport properties of Co nanoparticles embedded in a Cu matrix using x-ray absorption fine structure (XAFS) spectroscopy, macroscopic magnetization, and transport measurements. We observed by XAFS, on annealed samples containing 3, 10, 12, and 25 at. % Co, that there is a systematic contraction of the average coordination distance around Co atoms with the increasing Co content and annealing. The results are consistent with the growing of small fcc nanoparticles and correlated to the evolution in the superparamagnetic behavior, observed by magnetization measurements. We present a simple model to connect the diameter of Co nanoparticles to the average coordination distance and its mean-square fl...
