First-order phase transition and unexpected rigid rotation mode in hybrid improper ferroelectric (La, Al) co-substituted Ca3Ti2O7 ceramics

open access: yesJournal of Materiomics, 2019
Ca3Ti2O7 with Ruddlesden-Popper structure exhibits the largest polarization among the known hybrid improper ferroelectrics. However, the high Curie temperature impedes the thorough study of phase transition through dielectric characterization.

Wideband polarization-independent anomalous reflection metasurface with multiple resonance modes [PDF]

open access: yesJournal of Advanced Dielectrics, 2017
An ultra-thin metasurface is proposed to realize wideband polarization-independent anomalous reflection. The sub-wavelength resonator can produce different resonance modes, which are the result of the combined effect of dielectric and the metallic ...

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

open access: yesAdvanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...
