description	The invention provides a high-Tc high-frequency high-impedance MnZn ferrite material and a preparation method thereof.MnZn ferrite is formed by multi-stage sintering of main components and auxiliary modifiers, the main components are composed of iron oxide, zinc oxide and manganese oxide, the auxiliary modifiers are composed of calcium carbonate, silicon dioxide, tin oxide and other metal oxides, and the Tc high-frequency high-impedance MnZn ferrite material is prepared from the main components and the auxiliary modifiers. Main components and an auxiliary modifier are subjected to multi-stage sintering, so that crystal grains are promoted to uniformly grow in the ferrite sintering process, the particle size range of the ferrite crystal grains is reduced, the particle size distribution uniformity of the ferrite crystal grains is improved, the impedance performance of the ferrite is improved, and the ferrite has high Curie temperature, high magnetic conductivity and strong impedance performance; and the device
