Dielectric anomalies in the incommensurate phase of urea-doped thiourea
نویسندگان
چکیده
2014 Complex dielectric constant has been measured in the modulated phase of a OC(ND2)2-doped SC(ND2)2 single crystal. One can expect that the introduction of doping molecules strongly disturb the chains of hydrogen bonds in such a way that the modulated wave should be affected. In the incommensurate phase a new kind of memory effect is observed and when the variation of temperature is very slow a series of quasiperiodic anomalies is detected. J. Phys.
