Dielectric properties of bismuth-containing pyrochlores: A comparative analysis

open access: yesJournal of Advanced Dielectrics, 2022
The comparative analysis of the dielectric properties of bismuth-containing pyrochlores with different manifestation of atomic order/disorder was carried out. We examined the dielectric properties (including behavior in electric fields) of two pyrochlore
