Abstract
The resistance increase above the Curie temperature in n-doped BaTiO3 ceramics is due to blocking layers. These layers are due to acceptor states at grain boundaries. When increasing the acceptor concentration an additional resistance maximum occurs below the Curie temperature, which finally prevails the original resistance increase. This maximum can be explained by the normal theory if the nonlinearity of the dielectric properties inside the blocking layers is taken into account.Keywords
