Improved Current Densities in MgB2 By Liquid-Assisted Sintering
S. K. Chen, Z. Lockman, M. Wei +2
Polycrystalline MgB2 samples with GaN additions were prepared by reaction of Mg, B, and GaN powders. The presence of Ga leads to a low melting eutectic phase which allowed liquid p…
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…
The structure of the superconducting gap in MgB2 from point-contact spectroscopy
Y. Bugoslavsky, Y. Miyoshi, G. K. Perkins +9
We have studied the structure of the superconducting gap in MgB2 thin films by means of point-contact spectroscopy using a gold tip. The films were produced by depositing pure boro…
Microwave Power, DC Magnetic Field, Frequency and Temperature Dependence of the Surface Resistance of MgB2
A. A. Zhukov, A. Purnell, Y. Miyoshi +13
The microwave power, dc magnetic field, frequency and temperature dependence of the surface resistance of MgB2 films and powder samples were studied. Sample quality is relatively e…
Growth of Strongly Biaxially Aligned MgB2 Thin Films on Sapphire by Post-annealing of Amorphous Precursors
A. Berenov, Z. Lockman, X. Qi +10
MgB2 thin films were cold-grown on sapphire substrates by pulsed laser deposition (PLD), followed by post-annealing in mixed, reducing gas, Mg-rich, Zr gettered, environments. The…
Microwave Surface Resistance in MgB2
A. A. Zhukov, K. Yates, G. K Perkins +8
Measurements of the temperature dependence of the surface resistance at 3 GHz of 100 micron size grains of MgB_2 separated powder are presented and discussed. The microwave surface…
