“…3a and b, respectively. These values correspond well to those of the dot film prepared on MgO [9]. By increasing the substrate temperature for Fe deposition, the dot size increased to 15 nm and the number density was significantly reduced (Fig.…”

“…Therefore, to use quantum effects (i.e., CB and CS), homogeneous arrangement of nanodots is needed. Ernult et al reported a fabrication of self-assembled Fe dots epitaxially grown on MgO (001) [8,9]. Iron possesses high surface energy, so an island growth is expected.…”

“…The Fe layers were then observed by STM to clarify their structure in real space. The results are shown in figure 1 and confirm the 3D growth mode of Fe [12]. In the case of the samples designed with nominal thicknesses of 0.3 and 0.5 nm, STM images show well separated rounded particles.…”

“…We prepared nanoparticles of Au and Fe and Co by means of a self-assembly process. [37][38][39] When the metals were deposited on dielectric substrates, nanoparticles were formed at the initial stage of deposition. Nanoparticles with several radii were formed by changing the nominal deposition thickness.…”

We investigated the magneto-optical (MO) effect with localized surface plasmon resonance (LSPR) on ferromagnetic metal (Fe and Co) nanoparticles. We estimated the electric-field enhancement of the ferromagnetic metal nanoparticles caused by LSPR based on Mie scattering theory and compared it with that of Au nanoparticles. The electric-field enhancement of the ferromagnetic metal nanoparticles was 15–17, which is half of that of the Au nanoparticles. In order to explain the calculated results, we prepared ferromagnetic metal nanoparticles by a self-assembly process. We measured the optical transmission spectra and Faraday effect of the ferromagnetic nanoparticles. Although remarkable MO enhancement was not observed, we found characteristic MO spectra and a peak shift at wavelengths longer than 800 nm in samples whose thickness was less than 6 nm. We numerically investigated the size effect and reproduced the experimental results. We concluded that localized plasmons of ferromagnetic metal nanoparticles can produce electric-field enhancement, but the enhancement is not enough to increase the MO effect, and that the MO effect of nanosized ferromagnetic metals could be influenced by size effects rather than by LSPR.
