On the microscopic mechanisms behind hyperferroelectricity
Mohamed Khedidji, Danila Amoroso, Hania Djani
Hyperferroelectrics are receiving a growing interest thanks to their unique property to retain a spontaneous polarization even in presence of a depolarizing field. Nevertheless, ge…
Bi2W2O9: a potentially antiferroelectric Aurivillius phase
Hania Djani, Emma. E. McCabe, W. Zhang +5
Ferroelectric tungsten-based Aurivillius oxides are naturally stable superlattice structures, in which A-site deficient perovskite blocks [WnO3n+1]-2 (n = 1, 2, 3, ...) interleave…
Rashba spin-splitting in ferroelectric oxides: from rationalizing to engineering
Hania Djani, Andres Camilo Garcia-Castro, Wen-Yi Tong +4
Ferroelectric Rashba semiconductors (FERSC), in which Rashba spin-splitting can be controlled and reversed by an electric field, have recently emerged as a new class of functional…
Crystallization of Supercooled Liquid Elements Induced by Superclusters Containing Magic Atom Numbers
Robert Felix Tournier
A few experiments have already detected the presence of icosahedral superclusters in undercooled liquids, confirming a possible homogeneous nucleation of such entities as suggested…
Ultrasensitive microwave spectroscopy of paramagnetic impurities of sapphire crystals at millikelvin temperatures
Warrick G. Farr, Daniel L. Creedon, Maxim Goryachev +2
Progress in the emerging field of engineered quantum systems requires the development of devices that can act as quantum memories. The realisation of such devices by doping solid s…
First-principles study of the ferroelectric Aurivillius phase Bi2WO6
Hania Djani, Eric Bousquet, Abdelhafid Kellou +1
In order to better understand the reconstructive ferroelectric-paraelectric transition of Bi2WO6, which is unusual within the Aurivillius family of compounds, we performed first pr…
