Abstract

Perpendicular magnetic anisotropy (PMA) were investigated at low temperature in dc-magnetron sputtered NiCu/Cu multilayers. The thickness t⊥at which the multilayers change the preferential orientation form perpendicular to in-plane was found to be 55 nm. The experimental results show a strong perpendicular easy direction of magnetization for NiCu layer thickness between 4.2 nm and 34 nm. The structural analysis show that the low magnetostatic energy density is causing the large t⊥value obtained.
