Aspects of high temperature superconductivity
نویسنده
چکیده
2014 We present some remarks on special features that distinguish the phenomenology of the new high Tc oxides from that of the conventional superconductors. They include a measurable width of the critical region and a high sensitivity to crystallographic defects. A consistent Landau Ginsburg interpretation it possible, with a short coherence length 03BEab ~ 15 Å and a penetration depth 03BBL ~ 900 Å. The latter is somewhat smaller than the currently accepted value, and implies a broad band scheme. J. Phys. France 50 (1989) 2851-2856 15 SEPTEMBRE 1989,

Experimental aspects of Alpha, Beta angles distortion on superconductivity in 1111-type Iron-based superconductor
In this research, we aim to clarify the relationship between the structural distortion due to doping and the superconductivity existence in the FeAs4 structure. For this, we have prepared polycrystalline of NdFeAsO0.8F0.2, NdFeAs0.95Sb0.05O0.8F0.2 and Nd0.99Ca0.01FeAsO0.8F0.2 samples by one-step solid state reaction method. The structural and electrical properties of the samples were characteri...
متن کاملIntroduction to Unconventional Superconductivity
This lecture gives a basic introduction into some aspects of the unconventional superconductivity. First we analyze the conditions to realize unconventional superconductivity in strongly correlated electron systems. Then an introduction of the generalized BCS theory is given and several key properties of unconventional pairing states are discussed. The phenomenological treatment based on the Gi...

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...
متن کاملA Possible Theoretical Model For Studying Superconductivity In Fe-based Systems
A theoretical approach with a microscopic model is proposed for the observed ”high temperature superconductivity” in the Iron-based compounds. The above scheme takes into account two important aspects viz. (i) superconducting transition close to magnetic ordering and (ii) the layered structure. From the calculation of the superconducting transition temperature, it is shown that in the Fe-based ...

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 ...
متن کاملAnisotropic s-wave superconductivity: comparison with experiments on MgB2 single crystals
– The recently discovered superconductivity in MgB2 has captured world attention due to its simple crystal structure and relatively high superconducting transition temperature Tc = 39K. It is generally accepted that it is phonon-mediated s-wave BCS-like superconductivity. Surprisingly, the strongly temperature dependent anisotropy of the upper critical field, observed experimentally in magnesiu...
