Enhancement of Critical Current Density in low level Al-doped MgB2
A. Berenov, A. Serquis, X. Z. Liao +7
Two sets of MgB2 samples doped with up to 5 at. % of Al were prepared in different laboratories using different procedures. Decreases in the a and c lattice parameters were observe…
Superconducting gap structure and pinning in disordered MgB2 films
Y. Bugoslavsky, Y. Miyoshi, G. K. Perkins +7
We have performed a comparative study of two thin films of magnesium diboride (MgB2) grown by different techniques. The critical current density at different temperatures and magne…
The effect of magnetic field on the two superconducting gaps in MgB2
Y. Bugoslavsky, Y. Miyoshi, G. K. Perkins +4
Double-gap superconductivity in an epitaxial MgB2 film has been studied by means of point-contact spectroscopy in magnetic field up to 8 Tesla. The relatively fast disappearance of…
Effects of proton irradiation and ageing on the superconducting properties of single crystalline and polycrystalline MgB2
G. K. Perkins, Y. Bugoslavsky, A . D. Caplin +7
We present magnetisation data on crystalline and polycrystalline MgB2 before and after irradiation with ~1MeV protons. In the virgin crystal the critical current density is below o…
Critical Fields and Critical Currents in MgB2
A. D. Caplin, Y. Bugoslavsky, L. F. Cohen +4
We review recent measurements of upper (Hc2) and lower (Hc1) critical fields in clean single crystals of MgB2, and their anisotropies between the two principal crystallographic dir…
Effective Vortex Pinning in MgB2 thin films
Y. Bugoslavsky, L. Cowey, T. J. Tate +13
We discuss pinning properties of MgB2 thin films grown by pulsed-laser deposition (PLD) and by electron-beam (EB) evaporation. Two mechanisms are identified that contribute most ef…
