Abstract

Motivated by the recent advances with magnetic nanoparticles, in this research we propose a new technique for their characterization based on the measurement of certain polarimetric parameters of the scattered light, such as the linear polarization degree when it is determined at a “right-angle” scattering configuration. We will show the sensitivity of its spectral evolution with the magnetic properties of the particle.

Linear polarization degree at RASC ( P L ( 90 ° ) ) [solid line] and extinction efficiency ( Q ext ) [dashed line] of a spherical particle ( R = 100 nm ) as a function of the incident wavelength. Mie coefficients associated to resonances of the extinction efficiency are shown. Also, we have included the angular distribution of the scattered intensity for several cases ( λ = 400 , 526, 674, and 950 nm ).

Linear polarization degree measured at RASC, P L ( 90 ° ) [solid curve] of a spherical particle with radius (a) R = 100 nm , (b) R = 200 nm , (c) R = 300 nm , and (d) R = 400 nm as a function of the wavelength of the incident field. The corresponding extinction efficiencies ( Q ext ) are also plotted [dashed curve]. Mie resonances are marked with the Mie coefficients, whose maximum values are associated to each resonance.
