Electrical anisotropy in high-Tc granular superconductors in a magnetic field
D. Daghero, P. Mazzetti, A. Stepanescu +2
We propose an analytical model devoted to explain the anisotropy of the electrical resistance observed below the critical temperature in granular high-Tc superconductors submitted…

Barkhausen-like conductance noise in polycrystalline high Tc superconductors immersed in a slowly varying magnetic field
A. Masoero, P. Mazzetti, I. Puica +2
Analysis of the resistive transition of a polycristalline YBCO specimen produced by an a.c. magnetic field, reveals the presence of a large conductance noise signal which is repeti…
