Speed limit to the Abrikosov lattice in mesoscopic superconductors
G. Grimaldi, A. Leo, P. Sabatino +5
We study the instability of the superconducting state in a mesoscopic geometry for the low pinning material MoGe characterized by a large Ginzburg-Landau parameter. We observe…
Evidence of a new low field cross-over in the vortex critical velocity of type-II superconducting thin films
G. Grimaldi, A. Leo, D. Zola +4
We measure current-voltage characteristics as function of magnetic field and temperature in Nb strips of different thickness and width. The instability voltage of the flux flow sta…
Identification of the vortex glass phase by harmonics of the AC magnetic susceptibility
M. G. Adesso*, M. Polichetti, S. Pace
We compared the AC magnetic susceptibility behaviour for the vortex glass phase and for the creep phenomena with an inhomogeneous pinning potential. The temperature dependence of t…
Analysis of coupling losses in multifilamentary untwisted BSCCO/Ag tapes through a.c. susceptibility measurements
D. Zola, F. Gömöry, M. Polichetti +4
Losses as function of the a.c. magnetic field amplitude () were measured at 77 K in untwisted BSCCO(2223)/Ag tapes, at different frequencies, by measuring the imaginary part o…
Magnetic relaxation of type II superconductors in a mixed state of entrapped and shielded flux
D. Zola, M. Polichetti, C. Senatore +1
The magnetic relaxation has been investigated in type II superconductors when the initial magnetic state is realized with entrapped and shielded flux (ESF) contemporarily. This flu…
Irreversible Dynamics of Abrikosov Vortices in Type-two Superconductors
S. Pace, G. Filatrella, G. Grimaldi +1
The voltage shift RfIc with respect to the flux flow ohmic behavior of the current-voltage characteristic in type II superconductors is ascribed to the irreversible processes occur…
Third Harmonic Susceptibility and the Irreversibility Line of Fe/MgB2 Tapes
C. Senatore, N. Clayton, P. Lezza +3
We report a study of the pinning properties of Fe/MgB2 tapes performed by means of ac magnetic susceptibility measurements. In particular, the third harmonic response has been meas…
Vortex dynamics and pinning properties analysis of MgB2 bulk samples by ac susceptibility measurements
C. Senatore, M. Polichetti, D. Zola +3
The flux lines dynamics have been investigated on MgB2 bulk superconductors obtained by reactive liquid infiltration by measuring the ac magnetic susceptibility. The fundamental an…
