Glassy aging in the relaxor-like ferroelectric Na1/2Bi1/2TiO3

Research output: Contribution to journalArticlepeer-review


The dielectric susceptibility of the lead-free relaxor-like perovskite ferroelectric Na1/2Bi1/2TiO3 is shown to exhibit the same complicated spinglass-like aging behavior found in several cubic relaxors deep in the glassy state, in contrast to some uniaxial relaxors. The effects include rejuvenation and memory, including the ability to support multiple memories in parallel. Weak dependence of aging memories on changes in the electric field indicates that the aging is associated with relatively non-polar degrees of freedom, not with ferroelectric domains.
