Bismuth ferrite is a well-known multiferroic. It shows ferroelectric and antiferromagnetic ordering with a Curie temperature of ~1100 K and a Néel temperature of ~653 K. Bismuth ferrite’s properties can be altered through synthesis and doping. In this study, bismuth ferrite precursors were synthesized using three methods for comparison – a conventional shaker mill, a nano-agitator mill, and precipitation from solution. Each method was followed by calcination. Gadolinium and cobalt were used as dopants in the precipitation method. The composition, morphology, and magnetic properties of the resulting particles were characterized with SEM/EDAX, XRD, and VSM. The particles produced from the nano-agitator mill process had a more uniform distribution of grain sizes than the conventional shaker mill process. The particles produced through calcination method were large polygons covered in smaller facets. This method is faster, but there are few options available for modification with dopants when compared to the milling methods.
