AI Article Synopsis
- The study investigates the dielectric and impedance properties of compressively-strained multiferroic bismuth ferrite ceramics.
- The findings reveal that subsurface nanolayers called quasipolarons display a unique pressure-dependent transient frequency behavior.
- Additionally, a breakdown occurs in the expected relationship between complex permittivity and electrical impedance under pressure, challenging established principles in dielectric physics.
Article Abstract
We perform dielectric and impedance spectrums on the compressively-strained ceramics of multiferroic bismuth ferrite. The subsurface-nanolayer quasipolarons manifest the step-like characteristic of pressure-dependent transient frequency and, furthermore, pressure-dependency fails in the transformation between complex permittivity and electrical impedance, which is well-known in classic dielectric physics, as well as the bulk dipole chain at the end of the dissipation peak.
