Microwave Response of Coaxial Cavities Made of Bulk Magnesium Diboride
A. Agliolo Gallitto, P. Camarda, M. Li Vigni +3
We report on the microwave (mw) properties of coaxial cavities built by using bulk MgB2 superconductor prepared by reactive liquid Mg infiltration technology. We have assembled a h…
Carrier Transport in Magnesium Diboride: Role of Nano-inclusions
A. M. Awasthi, S. Bhardwaj, V. P. S. Awana +3
Anisotropic-gap and two-band effects smear out the superconducting transition (Tc) in literature reported thermal conductivity of MgB2, where large electronic contributions also su…
Microwave response of a cylindrical cavity made of bulk MgB2 superconductor
A. Agliolo Gallitto, G. Bonsignore, M. Li Vigni +2
We report on the microwave properties of a resonant cylindrical cavity made of bulk MgB2 superconductor, produced by the reactive liquid Mg infiltration process. The frequency resp…
Superconducting Microwave Cavity Made of Bulk MgB2
G. Giunchi, A. Agliolo Gallitto, G. Bonsignore +2
We report the successful manufacture and characterization of a microwave resonant cylindrical cavity made of bulk MgB2 superconductor (Tc = 38.5 K), which has been produced by the…
Effects of Weak Links in the Nonlinear Microwave Response of MgB2 Superconductor
A. Agliolo Gallitto, G. Bonsignore, G. Giunchi +1
We report experimental results of second-harmonic (SH) response at microwave frequency in several ceramic MgB2 samples, prepared by different methods. The SH signal has been invest…
Near-Tc second-harmonic emission in high-density bulk MgB2 at microwave frequency
A. Agliolo Gallitto, G. Bonsignore, G. Giunchi +1
We discuss the microwave second-harmonic generation in high-density bulk MgB2, prepared by the reactive liquid Mg infiltration technology. The intensity of the harmonic signal has…
