Magnetic field induced polarization effects in intrinsically granular superconductors
نویسنده
چکیده
Based on the previously suggested model of nanoscale dislocations induced Josephson junctions and their arrays, we study the magnetic field induced electric polarization effects in intrinsically granular superconductors. In addition to a new phenomenon of chemomagnetoelectricity, the model predicts also a few other interesting effects, including charge analogues of Meissner paramagnetism (at low fields) and ”fishtail” anomaly (at high fields). The conditions under which these effects can be experimentally measured in nonstoichiometric high-Tc superconductors are discussed. PACS numbers: 74.25.Ha, 74.50.+r, 74.80.-g Typeset using REVTEX 1

Novel Effects in High-tc Granular Superconductors Predicted by a Model of 3d Josephson Junction Arrays
Despite the fact that Josephson Junction Arrays (JAA) have been actively studied for decades, they continue to contribute to the variety of intriguing and peculiar phenomena (both fundamental and important for potential applications) providing at the same time a useful tool for testing new theoretical ideas. To give just a few recent examples, it is sufficient to mention paramagnetic Meissner e...
متن کاملINVESTIGATION ON THE EFFECTS OF MAGNETIC FIELD ON BROMIDE-INDUCED PITTING OF COMMERCIALLY PURE TITANIUM
Abstract: In chloride salt solutions, titanium alloys exhibit reasonably high pitting potentials as high as +10 V (vs. Ag/AgCl) at room temperatures. On the other hand, anodic pitting potentials are significantly lower in bromide solutions. In this study, pitting corrosion of commercially pure titanium in aqueous NaBr solution of 0.1 M concentration at room temperature was studied and the e...

We report systematic investigations of the magnetic superconducting properties of the new superconducting materials (NS): New high temperature superconductors (HTS), Organic superconductors (OS), fullerenes, carbon nanotubes, MgB2 etc. We show that, contrary to conventional superconductors where the superconducting state can be coherent over several tenths of km, the macroscopic coherence ran...
متن کاملInsulating state of granular superconductors in a strong-coupling regime
We analyze the possibility of the formation of a magnetic-field-induced insulating state in a two-dimensional granular superconductor with relatively strong intergranular coupling and show that such a state appears in a model with spatial variations of the single-grain critical magnetic field. This model describes realistic granular samples with a dispersion in grain sizes and explains the mech...
متن کاملSusceptibility in Granular Superconductors : Theory and Experiment
A phenomenological theory to describe the electromagnetic properties of granular superconductors, based on known bulk superconductors expressions and conventional Josephson’s junctions tunneling currents, is presented and successfully used to fit distinct experimental results for the magnetic susceptibility χ as a function of the temperature and the applied magnetic field of rather different sa...
