Abstract:

The FeAg and FePt/Ag thin films were deposited on SiO2〈0001〉substrates by direct current magnetron sputtering at room temperature.L10FePt granular films with high coercivity have been obtained after vacuum annealing at various temperature. The results indicated that adding Ag could reduce the FePt ordering temperature effectively,the transformation from disorder to order phase took place when the films were annealed at 300 ℃. With increasing the annealing temperature, the chemical ordering degree increased while the surface roughness of the samples decreased, forming uniform granular films.

Key words: metallic material, magnetic recording material, magnetron sputtering, L10FePt, structure, magnetic property
