摘要
研究了Ｎｉ－Ｚｎ铁氧体与锆钛酸铅ＰＺＴ复合材料在１～１０００ＭＨｚ范围内对电磁波的衰减情况。结果表明，ＰＺＴ由于具有铁电性与铁磁性共存特点，在１～１０００ＭＨｚ范围内有较好的吸波能力。在Ｎｉ－Ｚｎ铁氧体中添加ＰＺＴ后可提高Ｎｉ－Ｚｎ铁氧体在１００ＭＨｚ以下频段对电磁波的衰减能力。
The attenuation ability in the range 1～1000 MHz of composite consisting of PZT and Ni Zn ferrite was studied. It was found out that PZT is a kind of material that is both ferroelectric and ferromagnetic, so its attenuation ability is good. The attenuation ability of composite consisting of PZT and Ni Zn ferrite is greater than that of Ni Zn ferrite in the range below 100 MHz, which is not to be found in the range of 100～1000 MHz.
