78.30.-j - Opis:
- $BiFeO_3$ is a multiferroic material showing antiferromagnetic ordering and ferroelectric behavior simultaneously. Here, Mn-doped $BiFeO_3$ nanoparticles were synthesized up to 10% of Mn composition by a sol-gel process. The samples showed high crystallinity with no secondary phase up to 2% of Mn doping. A phonon peak at 1250 $cm^{-1}$ in undoped $BiFeO_3$ showed anomalous intensity enhancement in the magnetically ordered phase below $T_N$ = 643 K due to a spin-phonon coupling. This behavior was less pronounced in the Mn-doped samples, suggesting a suppression of magnetic ordering between $Fe^{3+}$ spins by Mn doping.
