Abstract :
In this paper, we investigate particle sizes and magnetic properties of FePt nanoparticles to determine if annealing at high temperatures for short times leads to the desired magnetic properties with reduced agglomeration. We used small angle neutron scattering and vibrating sample magnetometry for investigation.
