Extended x-ray-absorption fine-structure studies of heat-treated fcc-Fe_50Cu_50 powders processed via high-energy ball milling

The local structure and chemistry of a ferromagnetic fcc-Fe_50Cu_50 solid solution obtained through high-energy ball milling were measured before and after heat-treatment-induced decomposition using extended x-ray-absorption fine-structure measurements. The decomposition is first evident with the ph...
