Evidence of two ferroelectric PTCR components in valence-compensated ceramic system Ba1-xLaxTi1-xCoxO3

The electrical behaviour of valence-compensated ceramic system Ba1−xLaxTi1−xCoxO3 has been studied as a function of temperature (300–600 K) and composition (x ⩽ 0·20), using the method of impedance spectroscopy. The necessary equivalent circuit models that represent the data best have been obtained...
