Radiation-Induced Changes in the Structure and Magnetic Properties of Barium Hexaferrite
The effect of gamma irradiation and electron irradiation on the crystal structure and magnetic properties of barium hexaferrite BaFe12O19 (solid-phase synthesis) was studied. Irradiations caused changes in the ratio of crystalline phases and crystallite sizes, which resulted in changes in the main parameters of the hysteresis loop: coercive force, residual magnetization, saturation magnetization. These characteristics change nonmonotonically with varying dose, especially immediately after irradiation. In particular, the saturation magnetization measured at 300 K after γ-irradiation of the sample with a dose of 2.1 × 107 R decreased from the initial value of 52.5 to ∼40.2 emu/g.
