Abstract

The structures and magnetic characteristics of multilayered samples with alternatively deposited metal layers (Nd and Fe) were studied for 80 keV boron ion implantation to various doses. Boron ion implantation induced amorphization in Nd/Fe multilayers gradually with increasing irradiation dose. The hysteresis loops of magnetization of the samples showed that a sunken curve appear-ed in the second and fourth quadrants of the loops for the depo-sited Nd/Fe films and disappeared when implantation dose was more than 4*1016 B+/cm2. During ion irradiation, the coercive forces of the films were decreased. The saturation magnetization and the residual magnetization decreared first and then increased with increasing ion dose, the squareness ratio S. R increased first and then decreased. Discussion was carried out in this paper.
