Intergrain effects in the AC susceptibility of polycrystalline LaFeAsO_{0.94}F_{0.06}: comparison with cuprate superconductors
G. Bonsignore, A. Agliolo Gallitto M. Li Vigni, J. L. Luo +3
The AC susceptibility at zero DC magnetic field of a polycrystalline sample of LaFeAsO_{0.94}F_{0.06} (T_c = 24 K) has been investigated as a function of the temperature, the ampli…
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…
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…
Microwave Harmonic Emission in MgB2 Superconductor: Comparison with YBaCuO
A. Agliolo Gallitto, G. Bonsignore, E. Di Gennaro +3
We report results of microwave second-harmonic generation in ceramic samples of MgB2, prepared by different methods. The SH signal has been investigated as a function of the temper…
Microwave response of bulk MgB2 samples of different granularity
A. Agliolo Gallitto, G. Bonsignore, G. Giunchi +2
The microwave response of three high-density bulk MgB2 samples has been investigated in the linear and nonlinear regimes. The three samples, characterized by different mean size of…
