Abstract
The commensurate-incommensurate phase transitions were studied by NQR Cl in Rb2ZnCl4 and (NH4)2ZnCl4. It is found that structure of incommensurate phase is weak-modulated structure of ferroelectric phase. The “domain-like” structure near Tc and the region with single-wave modulation in vicinity of Ti were observed. The dT/dP and dΤ/dP values were obtained from NQR data under pressure. The nature of stabilization factors of incommensurate phase are discussed.Keywords
