- W4234326635 abstract "Measurements of pyroelectric current in needle shaped crystals of SbSexS1−xI (x ⪅ 0.01, x = 0.30, 0.33, 0.34, 0.38, 0.40, 0.50, 0.65) are carried out by measuring the potential difference across a short circuiting resistance while heating the samples at uniform rates. These measurements, together with dielectric constant show that the critical temperature (Tc) follows a rapid linear decrease when x increases up to 0.65 with a slope of 33 K per 0.1 of Se concentration. The spontaneous polarization deduced from measurement of the pyroelectric current seems consistent with a mean field theory. It is found that a critical point, where the order of the transition changes from first to second, occurs at a value of x around 0.30 ± 0.03. The fact that the spontaneous polarization does not go to zero at the critical temperature but rather decreases gradually when the temperature increases, for T > Tc may be attributed to composition fluctuations and internal stresses. Durch Messung der Potentialdifferenz über einen Kurzschlußwiderstand während der Proben-heizung mit konstanter Heizrate werden die pyroelektrischen Ströme in nadelförmigen SbSexS1−xJ (x ⪅ 0,01; x = 0,30; 0,33; 0,34; 0,38; 0,40; 0,50; 0,65)-Kristallen gemessen. Zusammen mit den Dielektrizitätskonstanten zeigen diese Messungen, daß die kritische Temperatur (Tc) einen starken linearen Abfall für x bis zu 0,65 aufweist, mit einem Anstieg von 33 K pro 0,1 Se-Konzentration. Die spontane Polarisation, bestimmt aus den Messungen des pyroelektrischen Stromes, scheint mit einer gemittelten Feldtheorie konsistent zu sein. Es wird gefunden, daß ein kritischer Punkt bei einem x-Wert um 0,30 ± 0,03 auftritt, wo die Ordnung des Übergangs von erster zu zweiter Art wechselt. Der Umstand, daß die spontane Polarisation bei der kritischen Temperatur nicht durch Null geht, sondern eher graduell abfällt, wenn die Temperatur für T > Tc zunimmt, läßt sich den Fluktuationen der Zusammensetzung und inneren Spannungen zuordnen." @default.
