Abstract
We show that moving dislocations generate giant effective local magnetic fields in a crystal lattice that can flip spins. Since massive creation of fast-moving dislocations is associated with a powerful elastic stress, this suggests a different mechanism of the magnetization reversal generated by laser or microwave beams or by electrically induced shear deformation.
