摘要
We analyzed the temperature dependence of the amplitude of modulated structures of [N(CH3)(4)](2)ZnCl4 crystal in the incommensurate (INC) phase by measuring the EPR spectra for Mn2+ doped single crystal. The amplitude of the vibrational modulation linearly increased with decreasing temperature. Applying Frank and Van der Merwe model, we simulated the EPR spectra in the INC phase. The simulated spectra agreed with the observed one very well. We, therefore, revealed that the vibrational modulation in this INC phase is due to the interaction between the harmonic chain of inter-particles and the modulation due to underlying potential which comes from the commensurate structure.
