Nuclear spin systems in manganites, having separation of ferromagnetic and antiferromagnetic phases, which are manifested as two lines in the NMR spectrum, are studied. Taking into account the Ising nuclear interaction, we obtain an analytical descri

An analytical expression is obtained for the amplitude of a nuclear echo signal generated in magnetically concentrated materials upon resonant excitation of the nuclear subsystem by two pulses with an equal amplitude. It is revealed that, when both t

It is theoretically established that multiple photon-echo signals reflect the oscillatory structure of the primary echo signal, which arises under the conditions of collinear excitation of two-level active centers by laser pulses having the same widt
