Low-frequency spectra of dislocation paths in NaCl crystals in the electron spin resonance scheme

Abstract

It is shown that the criterion of dislocation mobility resonance in NaCl crystals in the electron spin resonance scheme in the Earth's magnetic field depends on both the sample orientation in this field and the location of impurity atoms in the dislocation core. The measured lowfrequency spectrum of dislocation paths makes it possible to resolve a series of peaks corresponding to different positions of a Ca impurity that correlate with the results from computer simulations of the dislocation core structure.
