Specific optical eigenmodes are considered of finite clusters of metallic nanoparticles with plasmonic resonance as well as an
excitation transfer along linear chain of particles between clusters. Simple analytic and physically transparent results are presented for the problem solution of collective modes exciting inside two dimensional circular clusters and the problem excitation transfer
along one dimensional linear array of coupled small plasmonic spherical particles. The results are obtained with the aid of equations’
system for self-consistent currents excited inside particles by incident electromagnetic wave field. For circular cluster of particles the
coupling matrix between their currents becomes under definite conditions of such favorite properties that enables one immediately
to write out the Bloch–like eigenmodes with corresponding eigenfrequencies and their half widths. What is more we get also a
simple analytic expressions for coupling factor between inner part of a square structure arranged in a circular shape and its bound
part. Considering linear array of particles we use a closest neighbor interaction approach which makes the linear array like the
electric filter. In this approximation an analytic expression are obtained for extinction rate of exciting currents’ transfer depending
on array particles number and for resonance filtering frequencies. Hide Abstract

The optical spectra, thermal and magnetic properties of the compound SmCr$_3$(BO$_3$)$_4$ were investigated in a wide temperature
range. A series of phase transitions at temperatures of T$_1$ =8,0 ± 0,5К, T$_2$=6,7 ±0,5К and T$_3$=4,3 ± 0,2К. were found. First
two transitions at the temperatures T1 and T2 are second order phase transitions and, most likely, correspond to antiferromagnetic
ordering of subsystem Cr$^{3+}$ and, then, crystal transition to the ferroelectric state. First-order phase transition at a temperature of
4,2 ± 0,2K most likely corresponds to the spin-reorientation of the chromium magnetic moments. Hide Abstract
