Dielectric properties and conductivity in the systems BaTiO3-YBa2Cu3O7-δ and PbTiO3-BaPbO3

Ferroelectric solid solutions exist in the systems (I-x)BaTiO 3 -xY⅓Ba ⅔CuO 3−δ , (I) and (I-x)PbTiO 3 -xBaPbO 3 (II) in the concentration regions 0 ≤ x ≤ 0.02 (I) and 0 ≤ x ≤ 0.5 (II). The addition of the compounds with metallic conductivity deteriorates ferroelectric properties; it leads to the de...

Beschreibung
Zusammenfassung:Ferroelectric solid solutions exist in the systems (I-x)BaTiO 3 -xY⅓Ba ⅔CuO 3−δ , (I) and (I-x)PbTiO 3 -xBaPbO 3 (II) in the concentration regions 0 ≤ x ≤ 0.02 (I) and 0 ≤ x ≤ 0.5 (II). The addition of the compounds with metallic conductivity deteriorates ferroelectric properties; it leads to the decrease of the Curie temperature and the spontaneous polarization. Nevertheless, high polarizability still exist in the samples of the system I with x < 0.5.
