High coercivity and strongly (001) texture were obtained in FePt–C/FePt–SiO2 films.
Using FePt–C/FePt–SiO2 structure can get low magnetic coercive force distribution.
Columnar FePt grains with large aspect ratio were obtained in FePt–C/FePt–SiO2 films.
FePt–C/FePt–SiO2 films are very suitable for heat assisted magnetic recording media.
