按配方称取四氧化三锰、氧化锌、三氧化二铁混合料及经预分散处理过辅助组分按照1:1的比例掺配，投入砂磨机中，加入去离子水砂磨40分钟，抽至搅拌机中，加入浓度为4.5％的PVA溶液，搅拌3.5小时后，进行喷雾干燥，将干燥好的红色粉料在1650℃的温度下预烧4小时，得到预烧料；
(2)、预烧：
将上述得到的预烧料进行预烧，其中预烧温度为1100℃，预烧时间为200分钟；
(3)、造粒及成型：
将上述预烧后的预烧料放入砂磨机进行砂磨，砂磨时间为60分钟；砂磨后的浆料通过喷雾造粒机进行造粒，然后压制成型；
(4)、宽频低损耗复合磁性材料磁芯的制备
用压制模具将颗粒料按照已设计图纸外径、内径、厚度压制一定尺寸的生坯，将生坯置于1550℃的温度下，烧结2.5小时，即得到所需复合磁性材料磁芯。
