High-power low-loss gyromagnetic ferrite and preparation method thereof
The invention relates to a gyromagnetic ferrite with high power and low loss. The gyromagnetic ferrite is prepared according to the proportion of Y < 3-x-p-w > Ca < x > G < dp > Dy < w > Ge < x > In < y > Mn < z > Co < q > Fe < 4.97-x-y-z-q > O < 12 >, wherein 0.05 < = x < = 0.3, 0.01 < = y < = 0.1, 0.001 < = z < = 0.1, 0.05 < = p < = 0.7, 0.002 < = w < = 0.01, and 0.002 < = q < = 0.005. According to the invention, Y and Gd series are adopted as a basic formula, and the rectangularity of a hysteresis loop is improved through trace doping of Mn; the self-selection wave line width delta Hk is improved through combined substitution of Gd and Dy, so that high power is realized; the resonance line width delta H is reduced through small replacement of In and Mn, so that small loss is realized; the saturation magnetization intensity 4piMs is regulated and controlled through combination substitution of Gd, Ca and Ge; therefore, the device is suitable for different frequency devices. And the high self-selection wave line width delta Hk, the high residual magnetism ratio Rs and the low electromagnetic loss are achieved.
