Abstract
Theoretical aspects of electrically induced shifts of nuclear quadrupole resonance spectra are considered at ferroelectric phase transitions. The displacive and order-disorder types of phase transitions are analysed. Calculations and experimental data for the low-temperature phase transition in pyrargyrite (Ag3SbS3 show good agreement. It is confirmed that the above phase transition is of the order-disorder type. The phase transition is shown to be connected with the ordering of the silver ions in the double-minimum potential of the ionic bond S-Ag-S.
