Enhancing the dielectric, electrocaloric and energy storage properties of lead-free Ba0.85Ca0.15Zr0.1Ti0.9O3 ceramics prepared via sol-gel process
H. Mezzourh, S. Belkhadir, D. Mezzane +6
The Ba0.85Ca0.15Zr0.1Ti0.9O3 (BCZT) ceramics were successfully prepared by sol-gel process, and sintered at 1420 degree. The effect of sintering times (2, 4 and 6 h) on structural,…
Complex impedance and Raman spectroscopy of Na(BiDy)TiO ceramics
Manal Benyoussef, Moneim Zannen, Jamal Belhadi +4
In this work structural refinement, complex impedance spectroscopy, and Raman spectroscopy have been investigated on Na(BiDy)TiO (xDyNBT) ceramic sy…
Rare-earth effect on the physical properties of NaBiTiO system: A Density Functional Theory investigation
Manal Benyoussef, Halima Zaari, Jamal Belhadi +4
Na(Bi/4RE)TiO (RENBT, RE = Nd, Gd, Dy, and Ho) compounds were investigated in the framework of first-principles calculations using the full potentia…
Structural, dielectric, electrocaloric, and energy storage properties of lead free BaLa(ZrxTi)SnO (x = 0.05; 0.20) ceramics
Sihem Smail, Manal Benyoussef, Kamel Taïbi +3
A-site deficient BaLa(ZrxTi)SnO (x = 0.05; 0.20) ceramics (BLaZ100xTS) were synthesized using the solid-state reaction. The microstructu…
Mean field theory and Monte Carlo simulation of Phase transitions and Magnetic Properties of a tridimensional Fe7S8 Compound
S. Benyoussef, Y. EL Amraoui, H. Ez-Zahraouy +4
The structural, electronic and magnetic properties of Fe7S8 material have been studied within the framework of the ab-initio calculations, the mean field approximation (MFA) and Mo…
Quantification and Mapping of Elastic Strains Ferroelectric BaZrO3/BaTiO3 Superlattices
J. Belhadi, F. Ravaux, H. Bouyanfif +2
We report on quantification and elastic strain mapping in two artificial BaZrO3/BaTiO3 (BZ/BT) superlattices having periods of 6.6 nm and 11 nm respectively, grown on (001) SrTiO3…
