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…

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…

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…
