摘　　要：利用模压成型法制备了Fe73．5Cu1Nb3Si13．5B9非晶粉体／丁基橡胶和Fe73.5Cu1Nb3Si13．5B9纳米晶粉体／丁基橡胶复合薄膜，采用4284A阻抗分析仪在20～50℃测试温度范围内研究了复合薄膜的压磁性能。结果表明，复合薄膜在〈0．09MPa微应力、低于200kHZ测试频率下压磁性能最好；升高测试温度使复合薄膜的压磁性能增加，非晶粉体／丁基橡胶复合薄膜在40℃时压磁性能最好，纳米晶粉体／丁基橡胶复合薄膜在50℃时压磁性能最好；在相同条件下，非晶粉体／丁基橡胶复合薄膜的压磁性能优于纳米晶粉体／丁基橡胶复合薄膜。The composite films of amorphous Fe73.5 Cu1Nb3Si13.5B9 powders/butyl rubber and nanocrystalline Fe73.5Cu1Nb3Si13.5B9 powders/butyl rubber were prepared by means of molding to shape. The piezomagnetic property of composite film is studied in the temperature range of 20-50℃ by 4284A impedance analyzer. The results show when the compress stress being low 0.09MPa, and test frequency being low 200kHz, the piezomagnetic properties of films are the best; The piezomagnetic properties of composite films increase as temperatures increase, the piezomagnetic property of amorphous powder/butyl rubber composite film is the best at 40℃, and the piezomagnetic property of nanocrystalline powders/butyl rubber composite film is the best at 50℃; And the piezomagnetic property of amorphous powders/butyl rubber composite film is more excelled than nanocrystalline powders/butyl rubber composite film under the same conditions.
