Abstract
A strong effect of a static magnetic field B on active deformation kinetics (\(\dot \in \)=const) in LiF crystals is observed. This is a threshold effect with respect to B and \(\dot \in \); it is observed only for B> B c (B≃0.4 T) and \(\dot \in < \dot \in _c (\dot \in _c \approx 10^{ - 4} s^{ - 1} )\). Magnetic sensitivity is exhibited by the yield stress τ y , which decreases by approximately a factor of 1.5 for B=0.48 T, and by the stage-II and stage-III hardening coefficients θII and θ III, the former decreasing and the latter increasing in a magnetic field. A physical interpretation is proposed for the observed behavior.
