Abstract :
Partially ordered FePtAu nanoparticles with high coercivity are directly synthesized without post-annealing. Particle composition is determined by energy-dispersive X-ray analysis. The samples are also subjected to X-ray diffraction, room temperature magnetic hysteresis loops and dynamic coercivity measurements. Thermal stability factors and intrinsic coercivities are also determined.
