The Normal State Resistivity of Grain Boundaries in YBa2Cu3O7-delta
J. H. T. Ransley, S. H. Mennema, K. G. Sandeman +6
Using an optimized bridge geometry we have been able to make accurate measurements of the properties of YBa2Cu3O7-delta grain boundaries above Tc. The results show a strong depende…
Disorder induced collapse of the electron phonon coupling in MgB observed by Raman Spectroscopy
K. A. Yates, G. Burnell, N. A. Stelmashenko +4
The Raman spectrum of the superconductor MgB has been measured as a function of the Tc of the film. A striking correlation is observed between the onset and the frequ…
Effects of Ion Milling on the Microwave Properties of MgB2 Films
Sang Young Lee, J. H. Lee, J. Lim +4
The new superconductor MgB2 may prove useful for microwave applications at intermediate temperatures. MgB2 films with the thickness of 300 - 400 nm have surface resistance Rs less…
Josephson effects in MgB2 meta masked ion damage junctions
D. -J. Kang, N. H. Peng, R. Webb +8
Ion beam damage combined with nanoscale focused ion beam direct milling was used to create manufacturable SNS type Josephson junctions in 100 nm thick MgB with T of 38…
Planar Superconductor-Normal-Superconductor Josephson Junctions in MgB2
G. Burnell, D. -J. Kang, H. N. Lee +3
Since the discovery of superconductivity in MgB2 considerable progress has been made in determining the physical properties of the material, which are promising for bulk conductors…
Significant Reduction of the Microwave Surface Resistance of MgB2 Films by Surface Ion Milling
Sang Young Lee, J. H. Lee, Jung Hun Lee +6
The microwave surface resistance Rs of MgB2 films with the zero-resistance temperature of - 39 K was measured at 8.0 - 8.5 GHz. The MgB2 films were prepared by deposition of boron…
