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

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 proper...

Description
Summary: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. For instance, remanence and saturation magnetization of hard magnetic BaFe 12 O 19 increases by half. Similar behavior was also observed in the BiFeO 3 system. There are two possible explanations for these improvements: (1) Boron atoms reside between the grains and improve the links between grains or (2) Boron substitutes for iron atoms and changes magnetic anisotropy and thus magnetic parameters.
