The article presents the results of content analysis of content in 2014 when reporting on issues of corruption and how to counter it in five social networks: "Vkontakte", "Facebook", "Classmates”, "Twitter", "Live Journal" in Republic of Tatarstan of the Russian Federation. Different social networks have different purposes, but each contains conten...

The zero-field splitting of the S state due to the virtual electron transfer processes from the ligands into an unfilled shell of a paramagnetic ion has been calculated. A simple analytical formula has been deduced for the spin-Hamiltonian parameters. The paramagnetic centres: , , and with y = 0.91, 0.95 have been considered as an example. In all c...

In single crystals of LiCaAlF6 and LiSrAlF6 doped with Fe3+ the trigonal EPR spectra with multiplicityK M = 1 were observed due to Fe3+ substituted for Al3+. The spin Hamiltonian parameters describing the fine structure and the superhyperfine structure were determined. It is argued that the tensorsB 2 andB 4 of the spin Hamiltonian for Fe3+ ions ar...

In single crystal colquiriite LiCaAlF6 doped with Gd3+ ions two EPR spectra of the Gd3+ ions with the Laue site-symmetry groups Ci and C3i were observed. The spectrum angular dependence for trigonal Gd3+ centre was investigated in detail and corresponding spin Hamiltonian parameters were fitted. From analysis of the spin Hamiltonian tensorsB 4 andB...

The orientational dependences of the EPR spectra of Fe3+-doped LiCaAlF6 single crystals (space group P31c, Z=2), grown at the Laboratory of Magnetic Radio Spectroscopy at Kazan’ State University, have been investigated in detail. The spectrum is described by a trigonal spin Hamiltonian with the following parameters: B 20=40.07210−4 cm−1, B 40=−5.79...
