摘　　要：与铁氧体比较 ,所合成的有机磁性材料在很宽的温度范围 (- 2 71.5～ 12 0℃ )内磁性能十分稳定 ,在高频、微波下低磁损 ,重量轻 ,易热压成型 ,其导磁率 (μ′)和磁损耗 (μ″)基本不随使用频率和温度而变化 ,因此 ,适于制作许多高频、微波电子器件。As Compared with ferrites the magnetic performance of our organic magnetic material is very stable within -271.5～120℃ temperature range with low magnetic loss at high frequency and microwave frequency band. It is of light weight, does not necd high temperature sintering, can be easily hot pressed and shaped. Their magnetic conductivity (μ′) and magnetic loss (μ″) are basically unchanged under the variation of frequency and temperature,and it is suited for the manufactue of a series of high frequency and microwave frequency electronic devices.
