Abstract
The dislocation motion stimulated by a magnetic-field pulse in NaCl cr ystals is found to be associated with internal stresses. The magnetic field changes the states of point defects and dislocation cores. The d efects retain their new states after the magnetic field is turned off, which facilitates the dislocation motion. Presumably, the state of po int defects is susceptible to magnetic field because of the nonequilib rium occupancy of the energy levels, which, in turn, is caused by inte rnal strain.
