英文摘要：

Piezomagnetic effect of Fe-based amorphous alloy ribbon was studied by applying continuous stress to Fe-based amorphous alloy ribbon and testing the nearby closed loop inductance changes. The results show that the piezomagnetic property of Fe-base amorphous alloy ribbon can be characterized by testing the nearby closed loop inductance changes of Fe-base amorphous alloy ribbon. When the frequency was equal to lkHz, piezomag- netie property of Fe-based amorphous alloy ribbon has a good stability. And piezomagnetic property can be raised by increasing pressure. In the same pressure cases, Fe73. sCulNb3Si13, sB9 alloy ribbon has a better piezo- magnetic property than that of Fe78SigB13 alloy ribbon. When the frequency was equal to 100kHz, the piezomag- netic property of Fe73.5 Cu1 Nb3 Si13.5 B9 has a better stability than Fe78 Si9 B13 alloy ribbon Fe73. 5 Cu1 Nb3 Si13.5 B9 al- loy ribbon show the best piezomagnetic property when the frequency was equal to lkHz and the compressive stress was equal to 0.69MPa. When the compression stress was less than 0.1 MPa, the inductance of coil has a sharp rising trend with the increase of stress, Fe based amorphous alloy ribbon was more sensitive to tiny stress.
