N2 - BiFeO3 with 50–70 nm crystallites was obtained by glycine–nitrate combustion under varying conditions. These nanopowders demonstrated magnetic ordering at temperatures up to 400 K. The results were compared with the data known from other works, and it was shown that at the sizes lower than 70 nm the predominant contribution to the magnetization belongs to the crystallite surface. The effect of the increased magnetization, associated with the spin cycloid distortion, can also occur which, however, is less essential for crystallites of sizes ∼10 nm. For the first time, it was shown that the value of magnetization can be controlled technologically within several orders.
