TS单晶非公度相变膨胀系数的研究
THERMAL EXPANSION COEFFICIENTS OF THE INCOMMENSURATE PHASE OF BIS-(P-TOLUENE SULFONATE) OF,2,4-HEXADIYNE-1,6-DIAL SINGLE CRYSTAL
【摘要】 本文研究了 TS 从77K 到300K 膨胀系数与温度的关系,结果表明 TS 在非公度相变时膨胀系数出现明显反常.分析了 TS、PTS 的结构,指出侧链极性基团的运动在其中起重要作用.与铁磁性、反铁磁性材料类比,说明了反铁电性对膨胀系数的影响.
【Abstract】 The thermal expansion coefficients of TS have been studied.There appear the anomalies of thermal expansion coefficients during the incommensurate phase transition.TS and PTS structures has been analyzed.Experimental results show that the motion of the polar side group plays an important role in it.The effect of antiferroelectricity on thermal expansion coefficient is estimated by analogy from the antiferromagnetic system.
