Abstract: Magneto-dielectric response of semiconductor nanoparticles has been recently shown as a useful phenomenon for several applications, e.g. sensors. The enhancement and spectral tuning of this behavior is a keynote aspect for some of these approaches. In this work, we show that the Mie resonances of nanoparticles composed of AlxGa1-xAs can be enhanced and tuning in a fine way by controlling the relation between the particle size and the concentration of Al atoms (x).
