Organic and inorganic relaxor ferroelectrics with giant electrocaloric effect
Sheng-Guo Lu,Brigita Rožič,Qiming Zhang,Zdravko Kutnjak,Xinyu Li,Eugene Furman,Lee J. Gorny,Minren Lin,Barbara Malič,M. Kosec,Robert Blinc,Raša Pirc +11 more
TL;DR: In this article, the electrocaloric effect (ECE) in inorganic thin film and organic relaxor ferroelectrics is investigated by directly measuring the ECE around room temperature, and the results reveal that giant ECEs can be obtained in the high energy electron irradiated poly(vinylidene fluoride-trifluoroethylene) relaxor copolymer and in the La-doped Pb(ZrTi)O3 relaxor ceramic thin films, which are much larger than that from the normal ferroelectric counterparts.
Journal ArticleDOI
Comparison of directly and indirectly measured electrocaloric effect in relaxor ferroelectric polymers
Sheng-Guo Lu,Brigita Rožič,Qiming Zhang,Zdravko Kutnjak,Raša Pirc,Minren Lin,Xinyu Li,Lee J. Gorny +7 more
TL;DR: In this paper, the authors reported the directly measured electrocaloric effect (ECE) (the adiabatic temperature change ΔT) of relaxor ferroelectric poly(vinylidene fluoride-trifluorethylene-chlorofluoroethylene).
Journal ArticleDOI
Influence of the critical point on the electrocaloric response of relaxor ferroelectrics
Brigita Rožič,Marija Kosec,Hana Uršič,Janez Holc,Barbara Malič,Qiming Zhang,Robert Blinc,Raša Pirc,Zdravko Kutnjak +8 more
TL;DR: In this paper, the electrocaloric effect (ECE) was studied as a function of the magnitude of the electric field step E in the vicinity of the critical point in several bulk relaxor ferroelectric ceramic systems.
Journal ArticleDOI
Nanoparticle-induced widening of the temperature range of liquid-crystalline blue phases
Eva Karatairi,Brigita Rožič,Zdravko Kutnjak,Vassilios Tzitzios,George Nounesis,George Cordoyiannis,Jan Thoen,Christ Glorieux,Samo Kralj +8 more
TL;DR: Systematic high-resolution calorimetric studies reveal thatblue phase III is effectively stabilized in a wide temperature range by mixing surface-functionalized nanoparticles with chiral liquid crystals, yielding a robust method to stabilize blue phases, especially blue phase III.
Journal ArticleDOI
Bulk relaxor ferroelectric ceramics as a working body for an electrocaloric cooling device
Uroš Plaznik,Andrej Kitanovski,Brigita Rožič,Barbara Malič,Hana Uršič,Silvo Drnovšek,Jena Cilenšek,Marko Vrabelj,Alojz Poredoš,Zdravko Kutnjak +9 more
TL;DR: In this paper, the PMN-10PT relaxor ceramic exhibits a relatively large electrocaloric change of temperature ΔTEC> 1 K at room temperature, and the experimental testing of the cooling device demonstrates the efficient regeneration and establishment of the temperature span between the hot and cold sides of the regenerator.
