Experimental results are interpreted within the critical state model. Results deduced from vibrating reed technique are compared with ac susceptibility measurements. It is shown that both techniques give consistent resultsItem One-dimensional brownian-motion model for transport measurements in high-temperature superconductors(1996) Goupil, Ch.; Aouaroun, T.; Thopart, D.; Hamet, J. F.; Simon, Ch.Using a one-dimensional model of Brownian motion of vortices over pinning wells, we derive a current-voltage equation assuming a distribution of the effective pinning length. The model describes linear and nonlinear regimes of the E(J) curves in a single-particle description. Thermally activated flux flow and flux flow define the two limits of the dissipative process, respectively, at very low and high current. The pinning relief is described by pinning well depth and pinning well gradient, respectively, which can be checked by resistive and current-voltage measurements. The model is then applied to a YBa2Cu3O7−δ thin film. It provides a phenomenological model of the dissipation induced by transport currentItem Anisotropic resistivity measurements by a multi-terminal transport method(IOP Publishing, 1997) Aouaroun, T.; Hardy, V.; Goupil, Ch.; Warmont, F.; Villard, G.; Simon, Ch.Item Pillar defects, a new type of track in Pb-irradiated Bi-2212 thin films : nanostructural study and influence on the irreversibility line(Elsevier, 1998) H ebert, S.; Hervieu, M.; Hardy, V.; Aouaroun, T.; Simon, Ch.; Provost, J.; Milani, E.; Aruta, C.; Balestrino, G.Item Plastic vortex creep in the high-Tc superconductor (T1 2/3 , Bi1/3) Sr2CaCu2Ox(Elsevier, 1998) Aouaroun, T.; Hardy, V.; Simon, Ch.Item Vortex plastic creep in a superconducting crystal of Tl-2223(Elsevier, 1998) Aouaroun, Tahar; Simon, Charles
