A study was made of the resonance effect of a constant magnetic field, and of a superposed crossed variable magnetic field, upon the rate of macroplastic deformation and motion of edge dislocations. The frequencies of the variable magnetic field, at which the greatest variations in the plasticity of the crystals were observed, corresponded to the resonant frequencies for transitions between the Zeeman sub-levels in paramagnetic complexes of point defects and complexes that consisted of a point defect and a dislocation. Analysis of the radio-frequency spectra revealed the role that was played by intercrystal reactions in determining the mechanical properties of the crystals.
