MECHANISM OF FORMATION AND ENERGY TRANSFER IN MAGNETIC ROCKS OF KARACHAY-CHERKESSIA (NORTH CAUCASUS)

The mechanism of formation and energy transfer in rocks as crystals with impurity systems of donor and acceptor atoms is considered. An assessment was made of the times and concentrations at which the transfer process is not affected by the disorder of the acceptor environment and the decay is exponential. The question of the influence of excitation diffusion across donors on the rate of the process is also considered. A kinetic equation has been obtained that describes the evolution of the population of donor states averaged over impurity configurations in the presence of donor- donor interaction. This equation shows that the deactivation of donors accelerates and can take on an exponential character. It has been shown that the diffusion process in a disordered system proceeds more slowly than in an ordered one. Moreover, the diffusion of excitation through a disordered donor system determines the type of quenching. An equation for energy transfer in magnetic rocks ( crystals) was obtained and a condition corresponding to diffusion was found. An assessment was made of the times and concentrations at which the transfer process is not affected by the disorder of the acceptor environment and the decay is exponential. It is shown that the diffusion process in a disordered system proceeds more slowly than in an ordered one, and the diffusion of excitation through a disordered donor system determines its type. In the formation of energy transfer between impurities in magnetic crystals, the main role is played by the disorder of their arrangement along lattice sites. The transport equation in an ordered medium and the conditions of diffusion at the initial moment of the process are derived. It was found that in a disordered system of particles (rocks) connected to each other by short-range interactions, the main role is played by the disorder of their arrangement along lattice sites, and the law can only manifest itself in the absence of migration of donor excitations.
