Abstract: With the advent of the 5G era, the construction of a large number of base stations has an increasing demand for low loss, high frequency characteristics and high-power soft magnetic composite magnetic powder core. Meanwhile, the rapid development of wide band-gap semiconductor technology has put forward higher requirements for the miniaturization, high-frequency and high power density of electronic devices. However, few soft magnetic materials can meet the external environment requirements of third-generation wide band-gap semiconductors, which further restricts the development of next-generation electronic devices. In order to meet the development requirements, FeSiBCCr composite amorphous magnetic powder cores with excellent comprehensive soft magnetic properties were successfully prepared by compounding water-atomized FeSiBCCr fine amorphous powder with carbonyl iron powder (CIP) with high saturation magnetization (Ms). The results show that, compared with FeSiBCCr amorphous magnetic powder cores without composite CIP, Ms of FeSiBCCr composite amorphous magnetic powder cores increase to about 160 emu/g when the CIP content is 20% (mass fraction, the same below), and the overall improvement is about 6.7%. Under 100 Oe external DC field, the DC-bias performance of FeSiBCCr composite amorphous magnetic cores reaches 72%, which is improved by 10.8%. Under the condition of 0.05 T@100 kHz, the coer loss of FeSiBCCr composite amorphous magnetic powder core is reduced to 296 mW/cm3, and the overall decrease is 11.6%. The effective permeability and quality factor of FeSiBCCr composite amorphous magnetic powder cores are increased to 47.0 and 174, respectively, by 14.6% and 9.4%. The new FeSiBCCr composite amorphous magnetic powder cores with the different filling contents of CIP exhibit high Ms, low core loss and good DC-bias characteristics, which are expected to meet the needs of high-frequency and high-current devices, and thus have a good application prospect in high-frequency electromagnetic systems.
