Lattice phonon modes of the spin crossover crystal [Fe(phen)2(NCS)2] studied by THz, IR, Raman spectroscopies and DFT calculations
Eric Collet, Giovanni Azzolina, Tomoaki Ichii +9
[Fe(phen)2(NCS)2] is a prototype transition metal complex material, which undergoes a phase transition between low-spin (LS) and high-spin (HS) phases, induced by temperature, pres…
Persistent type-II multiferroicity in nanostructured MnWO4 ceramics
Pascaline Patureau, Remi Dessapt, Philippe Deniard +5
We show that the type-II multiferroic properties of bulk MnWO4 are kept in nanostructured ceramics of 50 nm grain size prepared via spark plasma sintering (SPS). This means that fe…
Very-low temperature synthesis of pure and crystalline lead-free Ba0.85Ca0.15Zr0.1Ti0.9O3 ceramic
Zouhair Hanani, El-Houssaine Ablouh, M barek Amjoud +3
The site-doping strategy of barium titanate (BaTiO3) is a promising way to develop new lead-free materials for energy with enhanced dielectric and piezoelectric properties. A novel…
Analysis of the Robustness of Conventional and Topologically Protected Edge States in Phononic Crystal Plates
Yabin Jin, Daniel Torrent, Bahram Djafari-Rouhani
In this work we theoretically study the interface acoustic states of resonators on a thin plate with topologically protected and conventional designs. Topologically protected inter…
First-principles study of (Ba,Ca)TiO and Ba(Ti,Zr)O solid solutions
Danila Amoroso, Andres Cano, Philippe Ghosez
(Ba,Ca)TiO and Ba(Ti,Zr)O solid solutions are the building blocks of lead-free piezoelectric materials that attract a renewed interest. We investigate the properties of the…
The Nitrogen concentration effect on Ce doped SiOxNy emission: towards optimized Ce3+ for DEL applications
F Ehré, C. Labbé, C Dufour +9
Ce-doped SiO x N y films are deposited by magnetron reactive sputtering from a CeO 2 target under nitrogen reactive gas atmosphere. Visible photoluminescence measurements regarding…
