Abstract
Abstract The representation invariant relative to spin rotations of the Hamiltonian of electrostatic electron interactions is derived for a dielectric. The temperature dependence of the exciton spectrum and that of the value of the site spin moment, 〈 S 〉, due to exciton‐magnon interactions are considered.
