摘要：
Mossbauer studies of perovskites Bi1-x La (x) FeO3 (x = 0, 0.10, 0.20, 0.61, 0.90, 1.00) were conducted at 295 and 87 K. The spatial spin-modulated structure (SSMS) observed in perovskites BiFeO3 and Bi0.9La0.1FeO3 leads to a specific distribution of hyperfine fields P(B) with two peaks. Substitution of La for Bi (x = 0.2) destructs the SSMS. The concentration dependences of the hyperfine field (B), isomer shift (E >) and quadrupole shift (delta) were measured. The iron ions are in the trivalent state. The local magnetic moments mu(Fe) of the Fe3+ ions are determined.
