We prepared bulk samples of metastable solid solutions with bcc and fcc structuresin the Fe-Cu system by using shock compression with mechanical alloying, and the magnetization and valence electron were measured and calculated. The saturation magnetic-moment curve versus mumber of electrons per atom at 0K was found to be reasonably similar to the-electrons/atom curve of other transition-metal binary systems.
