Abstract

FeCo nanoparticles with controllable shapes and narrow size distribution were fabricated by using a plasma-gas-condensation technique. Either cubic shape or spherical shape were obtained when the magnetic field distribution above the sputtering target were well controlled. Meanwhile, the size distribution of these FeCo nanoparticles was also controllable, and a narrow size distribution of 4.9% was obtained at the optimized conditions. The Fe-Co nanoparticles with different shapes showed different magnetic behaviors.
