Improved Current Densities in MgB2 By Liquid-Assisted Sintering (2005)

Chen, S. K., Lockman, Z., Wei, M., Glowacki, B. A., MacManus-Driscoll, J. L.

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 phase sintering and...

Surface oxidation of cube-textured Ni-Cr for the formation of a NiO buffer layer for superconducting coated conductors. (2003)

Effective Vortex Pinning in MgB2 thin films (2002)

Bugoslavsky, Y., Cowey, L., Tate, T. J., Perkins, G. K., Moore, J., Lockman, Z., ...

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 effectively to the...

The structure of the superconducting gap in MgB2 from point-contact spectroscopy (2001)

Bugoslavsky, Y., Miyoshi, Y., Perkins, G. K., Berenov, A. V., Lockman, Z., MacManus-Driscoll, J. L., ...

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 boron on a sapphire...

Microwave Power, DC Magnetic Field, Frequency and Temperature Dependence of the Surface Resistance of MgB2 (2001)

Zhukov, A. A., Purnell, A., Miyoshi, Y., Bugoslavsky, Y., Lockman, Z., Berenov, A., ...

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 easy to identify by...

Growth of Strongly Biaxially Aligned MgB2 Thin Films on Sapphire by Post-annealing of Amorphous Precursors (2001)

Berenov, A., Lockman, Z., Qi, X., Bugoslavsky, Y., Cohen, L. F., ...

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 films had Tcs in...
