Image of FIG. 1.
FIG. 1.

(Color online) Schematic diagram of the fabrication process of block copolymer lithography.

Image of FIG. 2.
FIG. 2.

(Color online) XRD spectra of the continuous FePt (bottom plot) and continuous FePt/Fe composite (top plot) films before patterning. Both of them show good L10 FePt (001) texture.

Image of FIG. 3.
FIG. 3.

The SEM plan-view images of patterned (a) FePt and (b) FePt/Fe composite structure. The diameter of the pillars is about 32 nm, with a size distribution of 8%, and the pitch is about 35 nm.

Image of FIG. 4.
FIG. 4.

TEM cross-sectional images of patterned (a) and (c) FePt/Fe composite structure and (b) FePt structure. The thicknesses of the corresponding layers are: CrRu (31 nm), Pt (2.6 nm), FePt (5 nm), Fe (4.9 nm), and Ru (3.6 nm).

Image of FIG. 5.
FIG. 5.

(Color online) The hysteresis loops of continuous (a) FePt and (b) FePt/Fe composite media and of patterned (c) FePt and (d) FePt/Fe composite media. The out-of-plane coercivities in these figures are (a) 3.3 kOe, (b) 0.78 kOe, (c) 8.6 kOe, and (d) 4.3 kOe, respectively.
