Electrostimulation of the magnetoplastic effect in LiF crystals by an “internal” electric field induced during indentation

Indented LiF crystals demonstrate a change in the length of the dislocation rosette rays during their exposure to jointly acting dc magnetic and electric fields. It is shown that magnetic field with induction B = 1 T causes the electrostimulation or electrosuppression depending on the magnitude and direction of the external electric field with respect to the “internal” electric field induced by the charge transfer due to dislocations moving during the indentation.
