Synthesis and AC magnetic susceptibility measurements of Fe(2−)Al O3 compounds

Abstract FeAlO 3 have orthorhombic unit cell and Pna2 1 space group. It is ferrimagnetic, magnetoelectric, and piezoelectric with strong magnetic anisotropy. Conventional ceramic and oxalic precursors routes require high temperatures and second phases appear in the final product. We prepared a nonstoichiometric serie by precipitation of an aqueous solution containing the precursor salts at lower temperature. X-ray diffraction, densities and AC susceptibility were measured.
