Detailed study of antiferroelectric (AFE) branch of mixed crystals Rb1 - x(NH4)xH2PO4 phase diagram x ≥ 0.74 has been carried out by means of Tl2 + EPR probe. The coexistence of two structurally nonequivalent centers of thallium in low-temperature

The results of the detailed study of the freezing process in the disorded ferro- and antiferroelectric RADP compounds by means of the Tl2+ EPR have been presented. The data obtained show that the distribution of the frozen local fields arises and bro

The TI2+ centers in K2SeO4 crystals have been shown to be the relaxing defects. The anomalous Tl2+ spectra temperature transformation have been treated in terms of long-range correlations induced by the soft or phason mode between the defects. The th

Kinetic equations, describing a dilute paramagnet in “bottleneck” (BN) conditions, are obtained in the case of spin-lattice mechanism of longitudinal and transverse relaxation of electron spins (direct processes). The spectral distribution functi

Using the methods of nonequilibrium statistics, equations are obtained that describe the saturation of a nonuniformly broadened ESR line taking into account the phenomenon of spectral diffusion under phonon bottleneck conditions. It is shown that the
