The transport properties and structure of the solid solutions formed in the (100-x) La0.8Sr0.2MnO3 (LSM)-x La0.95Ni0.6Fe0.4O3 (LNF) system were studied for the first time. The parent LSM and LNF perovskites and the solid solutions formed in the concentration ranges x<30 and 70 <= x <= 100 exhibited a rhombohedral structure. The unit cell volume of these solid solutions decreases with increasing LNF content. Formation of a new phase with an orthorhombic symmetry was observed in the concentration range 35 <= x <= 70. Lower transport properties of the (100-x) LSM-xLNF, 43 <= x <= 53, compositions as compared to the parent LSM and LNF perovskites can be explained with the formation of a new phase with orthorhombic structure. The (100-x)LSM-xLNF single phase perovskites possess metallic type of conductivity in a narrow concentration and temperature range. (C) 2008 Elsevier B.V All rights reserved. |
