抄録

A novel technique for fabricating a L1₀-FePt nanoparticle film in a magnetically isolated state is reported. An organic mixture, which stabilizes colloids, inhibits the nanoparticles from forming agglomerations during annealing at up to 800°C, and the resulting film shows the included FePt nanoparticles to be L1₀ phase and magnetically isolated. Such a film indicates a steep decline in coercivity with the temperature increase whereas the nanoparticles have a large uniaxial anisotropy energy density because of thermal relaxation that corresponds to the particle size.
