Polarization mechanism in filled tungsten bronze Ba4Sm2Ti4Nb6O30 with pinched P–E hysteresis loops

Ferroelectric transition and polarization characteristics were explored for filled tungsten bronze Ba4Sm2Ti4Nb6O30 ceramics with pinched P–E hysteresis loops. Two dielectric permittivity peaks were observed at around 553 and 486 K on heating and cooling cycles, respectively, with a large thermal hys...
