In this review, the recent progress as regards the energy storage performance of antiferroelectric ceramics, including PbZrO3-based, AgNbO3-based and (Bi,Na)TiO3-based are summarized. The low temperature sintering techniques and the charge-discharge properties of antiferroelectric ceramics are also discussed from a practical point of view.
Antiferroelectric materials with higher electric field, reduced energy dissipation and lower remanent polarization generally display excellent energy storage performance. In this work, Pb 0.98 La 0.02 (Hf x Sn 1−x) 0.995 O 3 lead-based antiferroelectric ceramics were synthesized by a rolling process.
Relaxor antiferroelectric (AFE) ceramic capacitors have drawn growing attention in future advanced pulsed power devices for their superior energy storage performance. However, state of the art diel...
The review will be of benefit for researchers in the area as it offers a quick overview of recent progress in the development of various kinds of antiferroelectric ceramics and their properties. It should also stimulate the development of novel antiferroelectric ceramics with high energy storage performance.

It is thus found that the EAFE- kV/mm to 10.57 kV/mm by varying the Sn content from 0.31 to 0.35 at a fixed Zr content of 0.58. As a result, Wre is significantly enhanced from 0.28 J/cm3 to 2.35 J/cm3 while η simultaneously increases from 31.5% to 86.1%. role in enhancing the energy storage properties of antiferroelectric materials.
In materials that exhibit antiferromagnetism, the magnetic moments of atoms or molecules, usually related to the spins of electrons, align in a regular pattern with neighboring spins (on different sublattices) pointing in opposite directions. This is, like ferromagnetism and ferrimagnetism, a manifestation of ordered magnetism.The phenomenon of antiferromagnetism …
In electromagnetics and materials science, atiferroelectricity is a physical property of certain materials. It is closely related to ferroelectricity; the relation between antiferroelectricity and ferroelectricity is analogous to the relation between antiferromagnetism and ferromagnetism.. An antiferroelectric material consists of an ordered (crystalline) array of electric dipoles (from the ...
In this chapter we study the basic concepts and properties of magnons in antiferromagnetic (AF) materials itially we present a brief introduction to AF materials and a semiclassical calculation of the equilibrium spin configuration in simple systems with two types of magnetic anisotropy: uniaxial and biaxial. Then we study the antiferromagnetic resonance and …
De DAT-Aparici Eficiente PLUS elektrische boiler 50 liter met SMART controller is een energiezuinige Anti-kalk boiler met energielabel B.

En los materiales que exhiben antiferromagnetismo, los momentos magnéticos de los átomos o moléculas, generalmente relacionados con los espines de los electrones, se alinean en un patrón regular con espines vecinos (en subredes diferentes) que apuntan en direcciones opuestas.Esto es, como el ferromagnetismo y el ferrimagnetismo, una manifestación del magnetismo ordenado.

In Analogie zur spontanen Magnetisierung beim Ferromagnetismus kann sich in bestimmten Materialien auch ohne Anlegen
Abstract: In this paper, a three-dimensional (3-D) deep-trench capacitor using anti-ferroelectric (AFE) Hf x Zr 1-x O 2 (HZO) is experimentally demonstrated as a promising option for embedded dynamic random-access memory (eDRAM) by showing (i) a successful 10ns polarization switching for read/write operations, (ii) maximum operating voltage less than 1.8V, (iii) retention …
Ferro-elektrische materialen zijn opgebouwd uit kristallen die een spontane elektrische polarisatie vertonen. Deze polarisatie kan worden omgekeerd door een extern elektrisch veld aan te leggen. Wanneer dat gebeurt, dan richten de elektrische dipolen (die in de kristalstructuur van het ferro-elektrisch materiaal worden gevormd) zich volgens de richting van …
Abstract: We successfully developed a high-performance FeFET memory device by integrating ZrO 2 anti-ferroelectric with IGZO channel for the first time. The replacement of conventional HfO 2 ferroelectric by anti-ferroelectric ZrO 2 effectively reduces the coercive field and boosts endurance. Furthermore, the IGZO channel allows for an interlayer free gate stack that lowers …
Wide ranges of absorbance spectra were measured to elucidate a difference in the antiferro-electric (AF) ordering mechanisms below 50 and 168 K in Cs 3 H(SeO 4) 2 and Cs 3 D(SeO 4) 2, respectively llective excitations due to deuterons successfully observed at 610 cm −1 exhibit a remarkable isotope effect. This indicates that the transfer state in the dimer of Cs 3 …
Hysteresekurve zufolge Ferroelektrizität. Ferroelektrizität kommt nur in Kristallen vor, in denen die kristalline Symmetrie eine polare Achse zulässt. Dadurch kommt es durch die Verschiebung verschieden geladener Ionen im Kristallgitter zur spontanen Polarisation. Die elektrische Polarisation in Ferroelektrika kann durch das Anlegen einer äußeren Spannung umgepolt …
Magnetization and susceptibility. The magnetic susceptibility, χ, of a solid depends on the ordering of spins.Paramagnetic, ferromagnetic, antiferromagnetic, and ferrimagnetic solids all have χ > 0, but the magnitude of their susceptibility varies with the kind of ordering and with temperature.
