Abstract
The structural state of the Cu80Co20 compound after mechanical alloying and a subsequent thermal treatment has been studied by NMR spectroscopy and X-ray diffraction as well as measurements of magnetic and magnetoresistive properties. The analysis of the data obtained suggests the presence of ultradispersed cobalt particles in the copper matrix. A partial dissolving of cobalt in copper is likely to take place in defect regions. Such a structure is responsible for superparamagnetism of the Cu80Co20 compound at kT > 150 K and for a considerable GMR effect (12% at T = 77 K). The shifting of X-ray peaks of the copper matrix can be related to a coherent conjugation of Cu and Co constituents.
