| The evolution of spin system with the Fermi character of the relevant excitations under the strong magnetic field pulse is presented. The nonlinear dynamic equations describing interaction of the system and external magnetic field are found. It is shown that under certain conditions the initial state of the resonantly absorbing system does not change after passing of the field pulse (similar to optical self-induced transparency in two-level molecular gas). |
