at 600 °C for 20 min. The surface morphology, phase structures and magnetic properties of Mo (50 nm)/[NdFeB (100 nm)/Co(y)]×10/Mo (50 nm) thin films were researched by AFM, XRD and VSM, respectively. The results show that the films show stronger perpendicular magnetic anisotropy. When the thickness of Co layers is 10 nm, the coercivity Hc⊥ is the maximum, 295 kA/m. However, for y=10-20, the reduced......
