Transport properties of LaSrNi1 − x ScxOy solid solutions

Synthesis, oxygen nonstoichiometry and total conductivity of (La,Sr)2(Mn,Ni)O4±

“…The total conductivity values for the most conductive LaSrNiO 4 [37] LaSrNiO 3.97 [38] S, μV/K T, °C materials, La 1.2 Sr 0.8 Mn 0.1 Ni 0.9 O 4+ δ , La 1.3 Sr 0.7 Mn 0.1 Ni 0.9 O 4+ δ , are of about 100 S/cm in the range 400-1100°C. The p-type small-polaron conduction in the La 2-x Sr x Ni 1-y Mn y O 4± δ series was established for y ≠ 0.…”

“…8, the minimum on S = f(T) dependence was also observed in La 2 NiO 4+ δ . For the system LaSrNi 1-x Sc x O 4± δ , Savchenko et al reported that the break of the slope of S = f(T) dependence occurred at 500°C for x = 0, 0.1, and 0.2: this was attributed to the beginning of active oxygen release from the studied samples [38].…”
