Magnetic Properties of FePt Nanoparticles Annealed With NaCl

FePt nanoparticles have the potential to extend the data density of magnetic recording beyond 1 Tbit/in 2 . The phase transformation from low anisotropy, face-centered cubic to face-centered tetragonal with high anisotropy is essential and complex. The samples measured in this paper were annealed in...

Description
Summary:FePt nanoparticles have the potential to extend the data density of magnetic recording beyond 1 Tbit/in 2 . The phase transformation from low anisotropy, face-centered cubic to face-centered tetragonal with high anisotropy is essential and complex. The samples measured in this paper were annealed in a mixture with fine ground (
