High thermal stability of carbon-coated L1_0-FePt nanoparticles prepared by salt-matrix annealing

摘要

Monodisperse Ll_0-FePt nanoparticles with size ranging from 3 to 8 nm were prepared by the salt-matrix annealing method. It was observed that the annealed particles have high thermal stability-no sintering occurred even when the particles were heated at 1
