Modified LaNiO 3 single phases of the A/B‐site substituted La(Ni 0.6 Fe 0.3 )O 3 perovskites with A=Ag + , Pb 2+ , and Nd 3+ and B=Mn 3+ and Ga 3+ sustaining at high process temperatures without decomposition were synthesized and their crystallinity, microstructure, and electrical resistivity were investigated. Electrical resistivity was used as an indicator to explore the response of single‐phase La(Ni 0.6 Fe 0.3 )O 3 to the different A/B‐site substitutions. The rationalized explanation for the variations of resistivity with substitutions was based on the band structure‐related tolerance factor or by its two independent lattice distances: d La−O and d Ni−O .
