Investigation of structural, optical, dielectric and magnetic properties of LaNiO3 and LaNi1−xMxO3 (M = Fe, Cr & Co; x = 5%) nanoparticles

In Situ Electrochemical Cobalt Doping in Perovskite-Structured Lanthanum Nickelate Thin Film Toward Energy Conversion Enhancement of Polymer Solar Cells

“…Moreover, the replacement of larger host cations (Ni 3+ with an ionic radius of 0.7 Å) with smaller dopant cations (Co 3+ with an ionic radius of 0.54 Å) results in a reduction of the interplanar distance. This substitution, in turn, leads to a slight shift of the diffraction peaks toward higher diffraction angles which demonstrates that Co has been incorporated into the lattice of perovskite successfully in LNC 0.05 O, and LNC 0.10 O samples (see Figure b). , Interestingly, as can be observed in the LNC 0.15 O sample, a reverse effect occurs, causing a shift of the diffraction peaks toward lower diffraction angles. This shift is due to the specific effects of Co 3+ doping in different proportions, leading to varying interplanar spacings and, consequently, altering the XRD patterns.…”

Understanding the Seebeck coefficient of LaNiO3 compound in the temperature range 300–620 K

“…For LaNiO 3 compound researchers reported that it has metallic and paramagnetic ground state [36][37][38][39]. In contrary, the ferromagnetic [40] and antiferromagnetic [41] correlation in LaNiO 3 are recently reported. LaNiO 3 has controversial magnetic and transport properties.…”

Evaluation of BaCo0.4Fe0.4Zr0.2−xNixO3−δ perovskite cathode using nickel as a sintering aid for IT-SOFC

“…It is also clear that no thermal process decomposition or evaporation occurred within the SOFC operating temperature range, which depicts that it is thermally stable for SOFC operating temperature. 45 It can be observed from the gure that electronic conductivity increased with the increased concentration of NiO. When NiO doped by decreasing the zirconium concentration, the ions of zirconium reduced in host BaCo 0 .…”
