Abstract
Abstract
This work is devoted to the study of the kinetics of electron spins excitation in solid-state dilute paramagnets in the process of transient nutations. Transitional nutations are the response of a system, initially in thermal equilibrium, to a suddenly applied very intense resonance field during its transition to a new stationary state. The decay rate of the signal is determined by the interaction of active spins with each other Γac (Δ, t) ∼ nac (Δ, t) and active spins with passive Γpas (Δ, t) ∼ npas (Δ, t). Therefore, the challenge is to find these concentrations. They are obtained by solving kinetic (rate) equations.
