Abstract—
Nanocrystalline La1 – xCdxFeO3 (x = 0, 0.05, 0.1, 0.15, 0.2) powders with a narrow homogeneity range (xmax = 0.09 according to X-ray microanalysis and X-ray diffraction data) have been synthesized via coprecipitation followed by thermal annealing at 950°C for 1 h. The addition of Cd2+ cations leads to a decrease in average crystallite size from 10–70 nm at x = 0 to 5–60 nm at x = 0.1 (according to transmission electron microscopy data). The synthesized nanocrystals have ferrimagnetic properties.
