Structure and magnetic hysteretic behavior of bio^mo.osyo.osfeoa (m = sm, gd)‎ multiferroic compounds

الملخص EN

The multiferroic compounds Bio.9Smo.o5Y0.o5Fe03 and Bio.9Gdo.o5Yo.o5Fe03 were prepared by the conventional ceramic method and were characterized by X-ray diffraction, vibrating sample magnetometry, and Fourier transform infrared spectroscopy.

The compounds were found to have the rhombohedral perovskite-like structure, accompanied by the existence of small amounts of BizFe^ and Bi24Fe2039 impurity phases.

The soft ferromagnetic behavior observed in these compounds is thought to arise from a minor impurity magnetic phase.

The Fourier transform infrared spectra revealed the mode characteristic of Fe-O stretching vibrations.
