The barium ferrite ultrafine particles were synthesized by coprecipitation in an aqueous solution with polyacrylic acid (PAA) as a protective agent. Thermal analysis by TGA/DTA showed that the precursor could yield barium ferrite after calcination above 700 β€’ C for 2 h. By analyses of the XRD and el
