Fabrication of Multilayered rm MgB 2 / rm Ni Thin Films and Their Flux Pinning Properties

We prepared the multilayered MgB sub(2)/Ni thin films with the Ni layer spacings of 32, 23 and 16 nm. The MgB sub(2)/Ni multilayer nanostructure was confirmed to be obtained from the scanning transmission electron microscope observation. The clear enhancement of J sub(c) was observed in the multilay...

Zusammenfassung:We prepared the multilayered MgB sub(2)/Ni thin films with the Ni layer spacings of 32, 23 and 16 nm. The MgB sub(2)/Ni multilayer nanostructure was confirmed to be obtained from the scanning transmission electron microscope observation. The clear enhancement of J sub(c) was observed in the multilayered MgB sub(2)/Ni thin film when the magnetic field was applied parallel to the film surface. Moreover, the peak position of F sub(p) - B curves shifted to higher magnetic field with decreasing the Ni layer spacing.
