Kucherenko M.G., Nalbandyan V.M. POLARIZABILITY SPECTRA OF NANOCLUSTERS OF TWO COMPOSITE PARTICLES IN AN EXTERNAL MAGNETIC FIELDOn the basis of exact solutions of the Laplace equations in anisotropic conjugated fields the expressions are obtained for the electric dipole tensor polarizabilities of two-layer spherical nanoparticles with different materials layers in an external magnetic field. Based on these expressions the frequency dependence of the polarizability of composites composition of the metal/dielectric and dielectric/metal are studied for different values of the induction magnetic field tion, the radii of the cores and shells of the globules. The values of the material parameters (plasma frequency of metals and dielectric constant of nondispersion dielectrics) typical of noble metal (Ag, Au), silicon dioxide (SiO2) and optical glass are used for calculations. It is established that the spectra of the polarizability of a cluster consisting of two spherical particles with metal cores have two plasmon resonance separated in frequency, while particles with dielectric cores and metallic shells  — four. The influence of external magnetic field on the spectra of electric polarizability nanoclay-the method of spherical composite particles of different composition and geometry is investigated. As in the previously studied case of a homogeneous conductive particles in a magnetic field the splitting of the spectral peaks into individual components, which led to the increase of the magnetic field diverge in the opposite directions of the frequency scale is observed for clusters. Optical properties of composite nanoclusters with magnetized plasma of metal components by various geometric parameters of the system are studied. It is found that the frequencies of plasmon resonances in the spectra of the polarizabilities of the clusters have a strong dependence on the thickness distribution of composite particles. The conclusion is made the enhanced possibility of a change in the spectral optical properties of cluster (control of the shift of the resonances and their intensity) by varying the geometric parameters of the composites and applying an external magnetic field.Key words: two-particle cluster polarizability, layered nanoparticles, magnetic field, plasmon resonance.
