The incremental permeability of MnZn ferrites increases with a DC-bias field slightly and then decreases. Regulating composition and additions properly can improve DC-bias property of MnZn ferrites.
在直流叠加场下,材料的磁导率称为增量磁导率,MnZn铁氧体磁芯的增量磁导率随外加直流场的增大先略有增大而后才减小;通过适当调整主配方及掺杂可以得到直流叠加特性良好的材料;较大的ΔB=Bs-Br是软磁铁氧体磁芯具有良好的直流叠加特性的前提。
