Modification of intergrain connectivity, upper critical field anisotropy, and critical current density in ion irradiated MgB2 films

S. D. Kaushik, Ravi Kumar, P. K. Mishra +3

We study the effect of 100 MeV Silicon and 200 MeV Gold ion irradiation on the inter and intra grain properties of superconducting thin films of Magnesium Diboride. Substantial dec…

Improved Hc2 in Bulk-Form Magnesium Diboride by Mechanical Alloying With Carbon

B. J. Senkowicz, J. E. Giencke, S. Patnaik +3

High energy milling of MgB2 pre-reacted powder renders the material largely amorphous through extreme mechanical deformation and is suitable for mechanically alloying MgB2 with dop…

Properties of MgB2 thin films with carbon doping

A. V. Pogrebnyakov, X. X. Xi, J. M. Redwing +10

We have studied structural and superconducting properties of MgB2 thin films doped with carbon during the hybrid physical-chemical vapor deposition process. A carbon-containing met…

High-field superconductivity in alloyed MgB2 thin films

V. Braccini, A. Gurevich, J. E. Giencke +24

We investigated the effect of alloying on the upper critical field in 12 films, in which disorder was introduced by growth, carbon doping or He-ion irradiation, fi…

MgB2 Energy Gap Determination by Scanning Tunneling Spectroscopy

T. W. Heitmann, S. D. Bu, D. M. Kim +13

We report scanning tunneling spectroscopy (STS) measurements of the gap properties of both ceramic MgB2 and c-axis oriented epitaxial MgB2 thin films. Both show a temperature depen…
