The Delta E effect was studied using Fe77B16Si5Cr2 amorphous ribbon, and asymmetry in the Delta E curves was created using micro magnets placed on the surface of the ribbon. Asymmetry was also observed in the vibration amplitude versus the magnetic field, and magnetization loops of amorphous ribbons with micro magnets were observed. The results show that the asymmetries in the Delta E curves and magnetisation loops are in agreement with each other. A linear change in vibration amplitude as a function of the applied magnetic field in the +/- 100 A/m region was observed, which is important for sensor applications.
