摘要：

Active deformation of LiF crystals in a dc magnetic field B is shown to produce strong plasticization, which is the more pronounced, the higher is the magnetic induction B and the lower the strain rate epsilon. The measured dependences of the yield point sigma(y) on B and epsilon find a reasonable explanation within a simple kinetic model based on the competition between the thermally activated and magnetically stimulated unpinning of dislocations from impurity centers.
