Dielectric Aging Effects in Doped Lead Magnesium Niobate: Lead Titanate Relaxor Ferroelectric Ceramics
contribute to aging in normal macro-domain ferroelectrics No obvious dielectric aging effects have been observed in pure .9Pb(Mgl13Nb2,3)03:. 1PbTi03 relaxor ferroelectric ceramics in this study. The addition of small amounts of MnO however, induces aging effects. Aging effects preferentially reduce the dispersive component of the weak field permittivities above the aging temperature. Isothermal aging rates are observed to increase with increasing doping level. Dielectric constants vs the logarithm of time at constant temperature level out with time. The origin of aging for this type of relaxor material can be explained in terms of the volume stabilization of the polar vectors in polar micro-regions by the defect dipoles introduced by the doping.
