FIG. 1.

MnAs film grown on GaAs. (a) Topography of the film with an rms roughness of 2.3 nm, (b) Magnetic field gradient measured with the AFM data; (c) FFT of the data in (a), with no evidence for order, (d) FFT of the data in (b), with two peaks due to the stripes.

scans of nanoparticles on MnAs film. (a) AFM data showing the linear alignment of the nanoparticles, (b) MFM data replace with: confirming alignment of the nanoparticles follows the magnetic order.

scans revealing long range alignment. (a) Topography data with (b) Fourier transform of the data presented in (a). The alignment results in two peaks in the FFT; (c) MFM, showing underlying MnAs domains, with (d) the Fourier transform of (c). The peaks in (d) match those of (b) confirming the dots line up with the MnAs domains.

FIG. 4.

nanoparticles on MnAs. (a) AFM, revealing no nanoparticle alignment, (b) FFT of the data in (a), (c) MFM, showing MnAs domains, (d) the Fourier transform of (c) confirming domain alignment. Taken together this shows the film magnetic order did not affect the nanoparticles deposition.
