摘要：

FePt nanoparticles (NPs) have been encapsulated in the insulating and protective oxide matrix, using a sol-gel process, in order to prevent particles from agglomerating and sintering during the heat-treatment process required for the L1(0) ordering. The microstructural and ferromagnetic properties of FePt/TiO2 nanocomposites were characterized. The presence of oxide-matrix leads to more homogeneous microstructures and better magnetic properties. The short range positional order of the FePt NPs can be preserved upon annealing at 700 degrees C to possess higher room-temperature coercivities (H-C = 3.7 kOe). Such nanocomposites with assemblies of high-coercivity magnetic nanoparticles are attractive for realizing new types of ultra-high-density data storage devices and magneto-composites.
