Field-induced suppression of the pi-band superconductivity and magnetic hysteresis in the microwave surface resistance of MgB_2 at temperatures near T_c
M. Bonura, A. Agliolo Gallitto, M. Li Vigni +1
We report on the magnetic-field-induced variations of the microwave surface resistance, R_s, in a polycrystalline MgB_2 sample, at different values of temperature. We have detected…
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…
Magnetic hysteresis in the microwave surface resistance of Nb samples in the critical state
M. Bonura, A. Agliolo Gallitto, M. Li Vigni
We discuss the hysteretic behavior of the field-induced variations of the microwave surface resistance in superconductors in the critical state. Measurements have been performed in…
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…
