The electric field dependence of the dielectric constant (dc-tunability) for PZT based- ceramics with excess and deficit of lead was investigated. Dense and homogeneous substituted PZT samples with moderate dielectric constant and low dielectric losses were prepared by solid state reaction. Their dc-tunability characteristics were investigated and the experimental data were discussed in terms of the Johnson model completed with a Langevin term that describes “extrinsic” contribution to the nonlinear (E) dependences..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
