BaRuO3(BRO) and BaIrO3(BIO) thin films were prepared by laser ablation, and the effects of preparation conditions on the structure, morphology and electrical conductivity were investigated. BRO thin films deposited at oxygen partial pressure (PO2) = 13 Pa and substrate temperature (Tsub) < 573 K were amorphous. At Tsub = 573 K, the rhombohedral BRO thin films with (110) orientation were obtained. BRO thin films prepared at Tsub = 773 K and PO2= 13 Pa exhibited the resistivity of 5x10-6 m and showed metallic conduction. BIO thin films deposited at PO2= 40 Pa and Tsub < 623 K were amorphous. Tsub > 623 K, the BIO thin films crystallized into a 6H structure were obtained. The resistivity of the BIO films at PO2= 40 Pa decreased from 1.4x10-2 to 4x10-4 m with decreasing Tsub from 1073 to 573 K.

The results of electrical conductivity measurements on Nb, W, and Mn-doped Gd2Ti2O7 are presented. A correlation between electrical conductivity, the oxygen partial pressure and type of dopants has been obtained. The source of the different PO2 dependence for Mn-doped material is discussed.
