Figures

Image of FIG. 1.
FIG. 1.

Experimental x-ray reflectivity data from the virgin (circle) and the ion-irradiated (square) with a dose of multilayer samples. Data for the irradiated sample are vertically shifted down by three orders of magnitude for clarity. The first-order Bragg peaks are shown in the linear scale in the inset.

Image of FIG. 2.
FIG. 2.

A cross-sectional TEM image of the virgin multilayer. Fourier transform of the marked square region is shown in the inset (a). Diffraction pattern due to the periodic multilayer stack is shown in the inset (b).

Image of FIG. 3.
FIG. 3.

A selected area transmission electron diffraction pattern from the multilayer. The indexed spots are from polycrystalline Pt.

Image of FIG. 4.
FIG. 4.

A HRTEM image from the virgin multilayer.

Image of FIG. 5.
FIG. 5.

A cross-sectional TEM image of the irradiated multilayer. Fourier transform of the marked square region of the TEM image is shown in the inset (a). Inverse Fourier transform of inset (a) is shown in the inset (b).

Image of FIG. 6.
FIG. 6.

A HRTEM image from the irradiated sample. The region with the planar spacing of is likely to be an FePt region.

Image of FIG. 7.
FIG. 7.

GIXRD pattern from the irradiated sample measured with x rays. The positions of the diffraction lines are indicated: Pt (1), FePt (2), and bcc Fe (3). Peak positions agree with the presence of FePt particles.
