The origin of ferroelectricity in magnetoelectric YMnO3.
TL;DR: This work identifies the nature of the ferroelectric phase transition in the hexagonal manganite, YMnO3, using a combination of single-crystal X-ray diffraction, thorough structure analysis and first-principles density-functional calculations, and suggests an avenue for designing novel magnetic ferroelectrics.
Journal ArticleDOI
Observation of ferrotoroidic domains
TL;DR: Here ferrotoroidic domains are spatially resolved by optical second harmonic generation in LiCoPO4, where they coexist with independent antiferromagnetic domains, related to multiferroics with magnetoelectric phase control and to other systems in which space and time asymmetry leads to possibilities for future applications.
Journal ArticleDOI
Hexagonal YMnO(3).
TL;DR: The crystal structure of hexagonal yttrium trioxomanganate has been determined at room temperature and at 180 K and it is isomorphous with LuMnO(3).
Journal ArticleDOI
Orbital-order-induced metal-insulator transition in La1-xCaxMnO3
Bas B. Van Aken,Oana D. Jurchescu,Auke Meetsma,Yasuhide Tomioka,Yasuhiro Tokura,Yasuhiro Tokura,Thomas Palstra +6 more
TL;DR: Evidence is presented that the insulator-to-metal transition in La(1-x)Ca(x)MnO3 near x approximately 0.2 is driven by the suppression of coherent Jahn-Teller distortions, originating from d-type orbital ordering.
Journal ArticleDOI
Outdoor Performance of Bifacial Modules by Measurements and Modelling
TL;DR: In this article, the authors present an outline of a model that calculates the outdoor performance of a bifacial module including optical, electrical and thermal aspects, and present the annual yield gain prediction based on measured characteristics of bif facial modules relative to south-facing tilted monofacial modules.
