Accurate Measurements of the Intrinsic Surface Impedance of Thin YBCO Films Using a Modified Two-tone Resonator Method
J. H. Lee, W. I. Yang, M. J. Kim +5
We propose a modified two-tone method that could be used for sensitive measurements of the intrinsic microwave surface impedance (Zs) of thin superconductor films and the tand of a…
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.…
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…
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…
