Аннотация
The magnetic properties of Bi(Fe1 − x M x )O3(M = Mn, Ti) solid solutions have been studied in magnetic fields of up to 11.2 × 103 kA/m, and the composition stability range of the R3c ferroelectric phase has been determined. The results indicate that partial Ti4+ substitution for Fe3+ leads to a transition from a modulated antiferromagnetic state to a homogeneous weakly ferromagnetic ferroelectric state (x = 0.08), whereas the Bi(Fe 1− 3+ Mn 3+ )O3 solid solutions do not exhibit weak ferromagnetism. Charge compensation in is assumed to be ensured by cation vacancies.
