Introduction. The purpose of this research is to observe and study the effects of temperature variations on the formation of and magnetic properties of Iron/Platinum (FePt) nanoparticles. We hope to find properties that will suggest that FePt particles can be used for magnetic recording in computer storage devices or as a replacement to currently used rare earth metals.. BY. D. PEGU.
