Improvement of Magnetic and Structural Properties of Some Ferric Compounds with Boron Addition

Journal of Superconductivity and Novel Magnetism, 2010
In the present study, we investigate the influence of boron oxide addition on magnetic and structural properties of some ferric compounds (BaFe 12 O 19 and BiFeO 3 ). Our studies have shown that small amounts of B 2 O 3 addition improve the crystalline structure, and thus improve the magnetic properties effectively.
