Structural and magnetic studies of nanocrystalline (Fe2Co)30Cu70 alloys

Abstract Structural and magnetic properties of nanocrystalline Fe2Co and (Fe2Co)30Cu70 alloys prepared by ball milling have been studied by X-ray, Mossbauer and magnetization measurements. The X-ray and Mossbauer results of Fe2Co milled alloy indicate a formation of pure BCC phase with Bhf of 36 T. Samples of (Fe2Co)30Cu70 alloys were prepared either by milling the mixture of Fe2Co alloy with pure Cu powder (series I) or by milling the elemental powder mixture (series II). The X-ray and magnetization results of the final material (series I and II) indicate the formation of alloy with TC at about (420±1) K. Heat treatment of samples I and II induces precipitation of single-domain particles in Cu matrix.
