The formation mechanism of a time order in the activated BiFeO3 multiferroic

• Self-organization processes of atomic displacements in the perturbed BiFeO3 multiferroic were found.
• Processes have oscillatory nature with period of a few days.

It was established experimentally that internal local pressure is the physical cause of the previously observed phenomenon of self-organization of atomic displacements in multiferroics of BiFeO3 type, activated by an external impulse action. Mössbauer spectroscopy on nuclei 57Fe was used as the main research method.
