“…PLD is vastly used for deposition of high quality oriented multicomponent oxide material thin films such as superconductors, ferroelectrics, dielectrics, ferrites and other perovskite materials such as SOFC cathode and anode [11][12][13][14][15]. Polycrsytalline La 0.6 Ca 0.4 Fe 0.8 Ni 0.2 O 3 − δ thick films (thickness of about 3 μm) with pyramid grains on YSZ substrates have been deposited using PLD by Ruiz et al [16]. In this paper, first we synthesized La 0.6 Ca 0.4 Fe 0.8 Ni 0.2 O 3 − δ powder by sol-gel method and studied its structural and electrical properties.…”

“…In addition, these materials also show exchange bias (EB) effects [13]. Most of the structural studies carried out on these RFe 1Àx M x O 3 (R ¼ rare earth and M ¼ transition metal ions) show them as having orthorhombic structure with space group Pbnm [11][12][13][14].…”

Structural and Raman study of PrFe 1Àx Ni x O 3 (0 x 0.5) thin films deposited on LaAlO 3 substrate by Pulse laser deposition is presented. Structural analysis by X-ray diffraction shows that these films are highly epitaxial grown along the c-axis with (0 0 l) orientation and have an orthorhombic structure with space group Pbnm throughout the doping range. From Raman spectrum, a new peak starts developing at around 574 cm À1 in this system with Ni doping. However, after x ¼ 0.3 Ni concentration, there is a decline in intensity of this observed peak and for x ! 0.3, it (this mode) becomes hard to resolve with other observed modes. The generation of this new peak (574 cm À1 ) in the other similar system (LaFe 1Àx Ni x O 3 ) with Ni doping is also observed. This study is a direct indication of a structural phase transition (SPT) or symmetry breaking in the present and related systems. The established orthorhombic structure for the present and related system is doubtful.

“…Fe-based perovskite oxides have also attracted much attention as possible alternatives to cobaltites due to their interesting transport properties. When the Fe fraction is higher than 0.5, the materials exhibit its highest electronic conductivity as observed for the LaNi 0.2 Fe 0.8 O 3 phase in which a conductivity of 135 S/cm, at 800°C, was obtained [42,43]. Calcium is another effective dopant for the A site, with low cost.…”

Perovskite Materials - Synthesis, Characterisation, Properties, and Applications

View full text Add to dashboard Cite

Perovskite-type oxides with the general formula ABO 3 have been widely studied and are utilized in a large range of applications due to their tremendous versatility. In particular, the high stability of the perovskite structure compared to other crystal arrangements and its ability, given the correct selection of A and B cations, to maintain a large oxygen vacancy concentration makes it a good candidate as electrode in solid oxide fuel cell (SOFC) applications. Utilizing this novel structure allows the engineering of advanced, effective electrolytes for such devices. This review details the development of current state-of-the-art perovskite-type oxides for solid oxide fuel cell (SOFC) applications.
