On the basis of the modified Granato-Lucke and Landau-Hoffman models by calculating the distribution function of the phonons it is shown that the strength of the effect of phonons upon dislocations is much greater than it would be in the case of thermodynamic equilibrium, when heated by 12K as it was measured in the experiment. The comparison between the theoretical results and the experimental data for nickel at measured values of experimental parameters clearly demonstrated that the proposed approach provides the results of the same order of magnitude as the experimental data. Therefore, the reasons for the influence of magnetic field on the plastic properties of nickel is obviously related to its influence on the dynamic behavior of dislocations. We purposely spent part of experimental research on the influence of nonstationary magnetic field (which varies in magnitude, but does not change sign) at stable temperature to eliminate the contribution to the change in the dislocation mobility in a magnetic field from the interaction of dislocations with mobile domain boundaries and thermal effects.
