“…The observed semiconducting-like ρ c (T ) and negative out-of-plane magnetoresistance have been discussed in terms of different models, such as c-axis tunneling with a strong suppression by charge fluctuations excited in the process of tunneling 14 , c-axis hopping with interplanar scattering 12 , a reduction of the density of states due to superconducting fluctuations 6,8,9 , and a pseudogap and/or spin gap opening in the density of states 7,11 . This is another striking feature of HTS.…”

“…Over the last few years, many theoretical and experimental investigations have been devoted to the transport properties of HTS. In particular, in the temperature region showing the semiconductinglike c-axis resistivity, most compounds reveal a negative out-of-plane magnetoresistance: the Bi 2 Sr 2 CaCu 2 O 8+δ (Bi2212) 1,6,7,8,9,10 , the La 2−x Sr x CuO 4 (LSCO) 11,12 , and the La-doped Bi 2 Sr 2−x La x CuO 6+δ (BSLCO) system 5,13 .…”

“…2 Application of a magnetic field results in a positive in-plane magnetoresistance ͑MR͒ ⌬ ab / ab (0)Ͼ0 that violates Kohler's rule 3,4 and a negative out-of-plane MR ⌬ c / c (0)Ͻ0. 5,6 Possible explanations for ⌬ ab / ab (0) include two different carrier scattering rates 7 far above T c and the magnetic-field suppression of superconducting order parameter fluctuations close to T c . 8 ⌬ c / c (0) has been interpreted in terms of a spin gap, 6 by interplane tunneling together with a renormalization of the carrier density of states as a result of superconducting fluctuations, 9,5 and several other models.…”

“…5,6 Possible explanations for ⌬ ab / ab (0) include two different carrier scattering rates 7 far above T c and the magnetic-field suppression of superconducting order parameter fluctuations close to T c . 8 ⌬ c / c (0) has been interpreted in terms of a spin gap, 6 by interplane tunneling together with a renormalization of the carrier density of states as a result of superconducting fluctuations, 9,5 and several other models. In this paper, we report simultaneous measurements of the anisotropic MR and their interpretation in a coherent model.…”

“…It is assumed that the inter-grain resistance in ceramic YBa 2 Cu 3 O x (5 % Ag), that prevents a high I cr from reducing by the presence of silver in granular spaces of the sample. Knowing how the vortexes move and arrange themselves under various conditions, such as temperature, magnetic field, stress-effects, and doping agent (Ag), and how these phenomena are influenced by the physical properties of the material will be critical in controlling the flux motion and maintaining the super current flow in these materials [13,18,22,23,53,[56][57][58][59].…”
