Abstract

We prepared the multilayered MgB₂ /Ni thin films with the Ni layer spacings of 32, 23 and 16 nm. The MgB₂/Ni multilayer nanostructure was confirmed to be obtained from the scanning transmission electron microscope observation. The clear enhancement of J_c was observed in the multilayered MgB₂/Ni thin film when the magnetic field was applied parallel to the film surface. Moreover, the peak position of F_P - B curves shifted to higher magnetic field with decreasing the Ni layer spacing.
