Abstract
Giant magnetostriction effect and magnetic properties of the amorphous alternant Tb/Fe/Dy(sample A) and Fe/Tb/Fe/Dy (sample B) nano-multilayer films had been studied. The magnetic hysteresis loops show that sample B has better magnetic properties than sample A, and easymagnetic direction changes from perpendicular to the film plane (sample A) to parallel to the film plane (sample B). The sample B has good low-field giant magnetostriction, and it is five times higher than sample A at H=0.12 T from 16 ppm to 82 ppm.
