Sol–gel synthesis and characterization of Co-doped LSGM perovskites

“…4 Following the initial discovery, [1][2][3][4][5] numerous experimental studies have been carried out on LSGM materials, which also include the effect of transition-metal doping. [6][7][8][9][10][11] It is generally believed that doping with a transition metal cation is undesirable for the ionic conductor due to the appearance of n-or p-type conduction. However, it was found that the oxide ion conductivity was also improved by doping Co for Ga in LaGaO 3 -based perovskites, 7 although hole conduction was detected at high oxygen partial pressures.…”

Magnetic study of interatomic interactions, synthesis, structural and mass spectroscopy investigations of lanthanum gallate doped with cobalt and magnesium

“…Moreover, the concentration and nature of the dopants drastically affect the conductivity. Nickel and cobalt containing systems are considered to be the best conductors and chromium and manganese containing systemsthe worst [2,[6][7][8][9][10][11][12][13][14][15][16][17][18]. The reasons of the influence of the dopants, as a rule, are not discussed.…”
