• The magnetic properties of MO-Fe_2O_3 oxide magnets (M=Ba, Sr and Pb) were observed, in which a part of MO were replaced with NaF and B_2O_3. The specimens were prepared from Fe_2O_3,NaF, B_2O_3 and BaCO_3 or SrCO_3,PbO. The first reaction was performed at 900℃ or 1000℃ for 2 hours, then these specimens were sintered at 1100∿1300℃ for 15 minutes. Under the conditions in which sintering was performed, especially at the composition Fe_2O_3/MO=5.3 and (NaF+1/2B_2O_3) /MO=0∿0.5,the magnetic remanence B_r and coercive force _bH_c, for instance, were 2350 Gauss and 1900 Oe. in the isotropic Ba-ferrite magnet, respectively, and specific magnetization σ of Ba-ferrite was 79 Gauss, and curie temperature of Ba-and Sr-ferrite were 470℃ and 475℃, respectively.
