Figure 4
The XRD spectra of a monolayer of FePt nanoparticles on a functional PEI or APTS substrate under different annealing temperatures. For comparison, the XRD of a 130 nm film of FePt nanoparticles annealed at 913 K is also shown at the bottom (open circle). Two vertical lines indicate the positions of two major FePt diffraction peaks, (100) and (220). |
