Abstract

The compounds Bi0.9Gd0.1Fe0.98Mg0.02O3, Bi0.9Sm0.1Fe0.98Mg0.02O3 and
Bi0.9Ba0.1Fe0.98Mg0.02O3 were found to have a rhombohedral perovskite-like structure. The
structural parameters were extracted from the X-ray diffraction data. Fourier transform
infrared spectroscopy revealed traces of the -Fe2O3 magnetic phase in the
Bi0.9Ba0.1Fe0.98Mg0.02O3 compound. The Bi0.9Gd0.1Fe0.98Mg0.02O3 and
Bi0.9Sm0.1Fe0.98Mg0.02O3 compounds were found to show a weak intrinsic ferromagnetic
behavior, whereas the ferromagnetism of the Bi0.9Ba0.1Fe0.98Mg0.02O3 compound was found
to be non-intrinsic in origin. The magnetic transition temperatures were found to be around
340 C.
