The Gd(Ba2-xPrx)Cu3O single phase polycrystalline samples with 0.00 ≤ x ≤ 1.00 were investigated for structural, electronic and flux dynamic properties. An unusual hump on the resistivity vs. temperature curve of the samples has been observed for particular values of Pr doping. We have found that the Ba atom substitution at the rare earth site could lead to superconductivity in some parts of ...
Abstract Two-dimensional electron gas systems (2DEGs) generated at the oxide interfaces that exhibit rich physics phenomena opened up an era for oxide-based electronics, photonics, and spintronics. The recent discovery of superconductivity plus strong spin-orbital coupling naturally existing in 2DEGs KTaO 3 (KTO) made KTO exciting platform interplay electronic spin degrees freedom to create exo...
NATURE | VOL 410 | 15 MARCH 2001 | www.nature.com 345 The onsets of the transitions are all in the vicinity of 36 K, the transition temperature for x 0:10. There is no bulk superconducting transition for x 0:3 and x 0:4. The data are interpreted as indicating that bulk superconductivity in single-phase material is suppressed for x greater than 0.10. The superconducting transitions observe...
Planar Josephson junctions provide a versatile platform, alternative to the nanowire-based geometry, for generation of Majorana bound states, due additional phase tunability topological superconductivity. The proximity induction chiral magnetism and superconductivity in two-dimensional electron gas showed remarkable promises manipulate Here, we consider junction involving skyrmion crystal show ...
in this thesis we will present three topics. we define approximate fixed points in fuzzy normed spaces. also we obtain some necessary and sufficient conditions on the existence of? -fixed points for ? > 0. at the continue some results about approximate fixed points for a class of non-expansive maps on g-metric spaces are obtained and we define approximate fixed points in partial metric spa...
In this research, the effect of addition of silicon carbide (SiC) nanoparticles on the improvement of the structural, superconductivity, magnetic, and flux pinning properties of high-temperature superconductor Bi1.6Pb0.4Sr2Ca2Cu3O10+θ (Bi-2223) was investigated. The Bi-2223 ceramic superconductor was prepared using the sol-gel method, and silicon carbide nanoparticles were modified by Azobisiso...
We demonstrate that crystalline color superconductivity may arise as a result of pairing between massless quarks and quarks with nonzero mass ms. Previous analyses of this phase of cold dense quark matter have all utilized a chemical potential difference δμ to favor crystalline color superconductivity over ordinary BCS pairing. In any context in which crystalline color superconductivity occurs ...
The recent observation of superconductivity with critical temperatures (Tc) up to 55 K in the pnictide RFeAsO(1-x)F(x), where R is a lanthanide, marks the first discovery of a non-copper-oxide-based layered high-Tc superconductor. It has raised the suspicion that these new materials share a similar pairing mechanism to the cuprate superconductors, as both families exhibit superconductivity foll...
