title = "The effect of Ca-doping on structure and microstructure of La0.7(Ba1-xCax)0.3MnO3",
abstract = "In this paper, we explore the structure and microstructure of La0.7(Ba1-xCax)0.3MnO3 (x = 0.1; 0.3; 0.5). These materials are one member of perovskite manganites materials. The general structure is R1-xAxMnO3 (R = rare earth, A = divalent atoms). Doping in A site or Mn site would impact to the structure and microstructure of these materials. It is called distortion crystal structure. This distortion would influence the transport properties of perovskite manganite materials. In this study, the materials were prepared by a sol-gel method. It is shown that increasing Ca concentration as doping in A site did not make any phase changing, but there are changes in lattice parameter of La0.7(Ba1-xCax)0.3MnO3. Scanning electron microscope (SEM) was used to determine microstructure of these materials. From this measurement, we know that all materials consist of closed packed grains with equiaxed grain morphology randomly oriented. The compositional purity of all materials is confirmed by Energy Dispersive X-ray (EDX). It is concluded that the presence of Ca-doping in La0.7(Ba1-xCax)0.3MnO3 is remaining single phase but affected the structure and microstructure of these materials. By using a core-shell model and bandwidth theory, there is a correlation between changes in structure and microstructure to the transport properties of these materials.",
