It is established experimentally that internal local pressure is the physical cause of the self-organization of atomic displacements discovered earlier in multiferroics of the BiFeO
3
type, activated by the action of an external impulse (γ-irradiation, electric shock). The main method of research is Mössbauer spectroscopy on nuclei of
57
Fe.
