Aging and stress-dependent dielectric properties of multiferroic bismuth ferrite ceramics

Dielectric aging and stress-dependent dielectric properties of bismuth ferrite (BFO) and manganese (Mn)-doped bismuth ferrite (BFMO) ceramics were investigated. The dielectric properties of BFO ceramics were decreased significantly with the compressive stress, while the changes were reversed for the...
