分别以FeCuNbSiB和FeSiB非晶粉为粉体与硅橡胶复合,制成具有压磁效应的复合薄膜。利用4284A阻抗分析仪对两种薄膜的压磁特性进行了研究。研究表明,非晶FeCuNbSiB粉体/硅橡胶和FeSiB粉体/硅橡胶复合薄膜均具有良好的压磁性能,对于FeCuNbSiB粉体/硅橡胶复合薄膜,在压应力〈0.6MPa,频率低于200kHz的条件下,压磁效应敏感;对于FeSiB粉体/硅橡胶复合薄膜在0～1.45MPa内,薄膜的压磁效应变化幅度比较均匀;薄膜中粉体含量越高,复合薄膜的压磁效应越大,当含量为83.3%（质量分数）时,压磁性能最好;相同条件下,以FeCuNb-SiB为粉体制成的复合薄膜的压磁性能优于以FeSiB为粉体制成的薄膜的压磁性能。
The piezomagnetic films were prepared by FeCuNbSiB or FeSiB amorphous powders and silicone rubber.The piezomagnetic properties of the samples were tested by the 4284A impendance analyzer.The results show that both FeCuNbSiB/ silicone rubber films and FeSiB/ silicone rubber films have excellent piezomagnetic properties.For FeCuNbSiB/ silicone rubber films,the composite films have sensitive piezomagnetic properties when the compress stress being low 0.6MPa and test frequency being low 200kHz.The piezomagnetic property is always good between 0-1.45MPa for the FeSiB/ silicone rubber films.It is also found that the content of powders is higher,the piezomagnetic property of films is better,especially when the content is 83.3%,the piezomagnetic property is up to the maximum.The piezomagnetic property of FeCuNbSiB/ silicone rubber films is superior to FeSiB/silicone rubber films under the same conditions.
