摘要：

The evolution of nano-scale Fe particles precipitated in a Cu-Fe alloy has been examined from the viewpoint of the relationship between the microstructure and magnetic properties, using conventional, high-resolution and Lorentz electron microscopy, and magnetic measurements. It has been revealed that spherical Fe particles have a tendency to align along the < 001 > direction in a Cu matrix at the early stage of precipitation. A twin-like structure developed when spherical Fe particles grew to approximately 40 to 60 nm in size. Lorentz microscopy was successfully applied to determine the direction and magnitude of the magnetic momentum of Fe particles.
