Abstract

The frequency spectra of the dislocation decrement of attenuation ∆ d(f) on KCl + Ba (10-2 wt.%) impurity single crystals with residual deformations ꜫ of 0.25; 0.45; 0.75% at T = 300 K were investigated by the pulse method in the frequency range 22.5… 232.5 MHz. In the framework of the Granato-Lucke theory, the coefficients of dynamic drag of dislocations B for crystals with different ꜫ are calculated. It is shown that neither the presence of impurities nor the change of the dislocation structure affects the level of dynamic drag of dislocations.
