RELATIONSHIP BETWEEN MICROSTRUCTURE AND JC PROPERTY IN MGB2/Α-AL2O3 FILM FABRICATED BY IN SITU ELECTRON BEAM EVAPORATION
(IOP, 2005-08-09)
A transmission electron microscopy (TEM) study has been carried out on an MgB2/α-Al2O3 film that exhibits the typical property of critical current density (Jc) under magnetic fields. The MgB2 layer of 300 nm in thickness ...
MgB fiLMS WITH VERY HIGH CRITICAL CURRENT DENSITIES DUE TO STRONG GRAIN BOUNDARY PINNING
(American Institute of Physics, 2004-08-13)
MgB2 superconductor has a great potential for applications because of its high Tc and Bc2, exceeding those of any Nb-base superconductors at any temperature. It is now important to understand its flux pinning so as to raise ...
PROPERTIES OF MGB FILMS WITH VERY HIGH TRANSPORT CRITICAL CURRENT DENSITIES
(IEEE, 2005-06)
Magnesium diboride, MgB2, thin films are fabricated through two different kinds of process. One is an in-situ process by using electron beam deposition and the other is an ex-situ process by using the combination of pulsed ...
FABRICATION OF MULTILAYERED MGB2/NI THIN FILMS AND THEIR FLUX PINNING PROPERTIES
(IEEE, 2009)
We prepared the multilayered MgB2/Ni thin films with the Ni layer spacings of 32, 23 and 16 nm. The
multilayer nanostructure was confirmed to be obtained from the scanning transmission electron microscope observation. The ...
