Abstract

Mössbauer absorption spectra of single phase LaNi 1 - xFe xO 3 (0.2 ≤ x ≤ 1.0) have been measured. Increase of quadrupole splitting with increasing x from 0.2 to 0.6 suggested successful substitution of Fe ion for Ni. Variation of isomer shift with x suggested valence of Fe approched 4+, i.e., concentration of itinerant hole on Fe increased with decrease of Fe content, showing agreement with increase of electrical conductivity with decreasing x from 1.0 to 0.4. It can be prospected that higher electrical conductivity might be obtained if sintering property of the specimens with x less than 0.4 is improved.
