FePt multilayer films were prepared by magnetron sputtering on a Si substrate, both with and without a B4C underlayer, and subsequently annealed in vacuum. Experimental results suggest that the metal atoms (Fe atoms are in the majority) will diffuse through the native SiO2 layer on Si and then into the substrate with an increase in annealing temperature in the case without a B4C underlayer. The formation of silicides at a high annealing temperature leads to a sharp decrease in coercivity. Due to the effective separation of FePt films by B4C underlayers, the unusual decrease in coercivity is absent when they are annealed at an elevated temperature. The existence of the B4C underlayer and much more sufficient interdiffusion induces the coercivity to increase gradually to 8.1 kOe with the increase in the number of FePt layers.
