Highly oriented multiferroic Ba2NdFeNb4O15 -based composite thin films with tetragonal tungsten bronze structure on silicon substrates

, 2017
Multiferroic Ba2NdFeNb4O15-based composite thin films have been deposited on Pt/Si(100) substrates by pulsed laser deposition. Structural investigation demonstrated the achievement of highly c-oriented thin films of Ba2NdFeNb4O15 upon optimization ...

Excellent energy-storage performance realized in SANNS-based tungsten bronze ceramics via synergistic optimization strategy

Journal of Materiomics
A series of tungsten bronze (Sr2–xBixAg0.2Na0.8) (Nb4.8–xZrxSb0.2)O15 compounds were fabricated by solid-state method to systematically study the impacts of co-doping Bi3+/Zr4+ ions in A/B-sites on the structures, relaxor characteristics, and energy ...

Dielectric properties of tetragonal tungsten bronze films deposited by RF magnetron sputtering

, 2014
Tetragonal tungsten bronze (TTB) films have been synthesised on Pt(111)/TiO2/SiO2/Si substrates from Ba2LnFeNb4O15 ceramics (Ln = La, Nd, Eu) by RF magnetron sputtering.

Probing Mg Intercalation in the Tetragonal Tungsten Bronze Framework V₄Nb₁₈O₅₅ [PDF]

, 2020
While commercial Li-ion batteries offer the highest energy densities of current rechargeable battery technologies, their energy storage limit has almost been achieved. Therefore, there is considerable interest in Mg batteries, which could offer increased

Phase Separation and Phase Transitions in Multiferroic K_0.58FeF₃ with the Tetragonal Tungsten Bronze Structure

, 2011
The tetragonal tungsten bronze (TTB) structure multiferroic fluoride K058FeF3 (alternatively K3-xFe5F15 (x approximate to 0.1)) has been studied using variable temperature high-resolution synchrotron powder X-ray diffraction. The as-made sample occurs as

Structure-property relationships in ferroelectric tungsten bronze oxides

, 2019
Tungsten bronze-type compounds have been extensively studied as ferroelectric materials. Due to their large degree of compositional flexibility, focus has historically been on the tetragonal (TTB) structure. The hexagonal (HTB) structure has been studied

Quantifying Emptiness: On the Size of A-Site Vacancies in Tetragonal Tungsten Bronzes

Chemistry of Materials
Tetragonal tungsten bronzes (TTBs) represent the second largest family of ferroelectric materials and are charac- terized by their range of lattice sites and ability to have filled or vacant sites. However, the impact of empty A-sites (cation vacancies) on the stability and properties of TTBs has not been investigated so far.
