Magnetic susceptibility for ferrite Bi25FeO39 is measured at 5–950 K in the magnetic field of 0.86 T. It is shown that Bi25FeO39 is paramagnetic in the temperature range 5−950 K. The saturation magnetization is equal to 5.04μB per formula unit at 5 K in a magnetic field of 10 T. It is found that at 5−300 K the effective magnetic moment of Fe3+ ions in Bi25FeO39 is equal to 5.82μB.
