Effects of the Two- Gap Nature on the Microwave Conductivity of 39 K Polycrystalline MgB2 Films
Sang Young Lee, J. H. Lee, Jung Hoon Han +4
The surface resistance (Rs) and the real part (sigma_1) of the microwave complex conductivity of a ~380 nm-thick polycrystalline MgB2 film with the critical temperature (Tc) of 39.…
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…
A Directly Coupled Superconducting Quantum Interference Device Magnetometer Fabricated in Magnesium Diboride by Focused Ion Beam
G. Burnell, D. -J. Kang, D. A. Ansell +4
We report the fabrication of a directly coupled superconducting quantum interference device (SQUID) magnetometer in MgB2 using a focused ion beam (FIB) to create Josephson junction…
Recent developments in the characterization of superconducting films by microwaves
M. A. Hein, M. Getta, S. Kreiskott +7
We describe and analyze selected surface impedance data recently obtained by different groups on cuprate, ruthenate and diboride superconducting films on metallic and dielectric su…
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…
High critical current densities in superconducting MgB2 thin films
S. H. Moon, J. H. Yun, H. N. Lee +4
Superconducting MgB2 thin films were prepared on Al2O3(0001) and MgO(100) substrates. Boron thin films were deposited by the electron-beam evaporation followed by post-annealing pr…
