Superconductivity in the PbO-type Structure α–FeSe
The recent discovery of superconductivity with relatively high transition temperature (Tc) in the layered iron-based quaternary oxypnictides La[O1 xFx] FeAs by Kamihara et al. [Kamihara Y, Watanabe T, Hirano M, Hosono H (2008) Iron-based layered superconductor La[O1-xFx] FeAs (x 0.05–0.12) with Tc 26 K. J Am Chem Soc 130:3296–3297.] was a real surprise and has generated tremendous interest. Alt...

متن کاملSuperconductivity and the new Fe Based Superconductors
The Imperial College group has a long-established programme on superconductivity, going back to before the discovery of the high temperature superconductors (HTS) in 1986, evolving from vortex physics, superconducting critical current density and distribution of critical current in wires and tapes for power transmission, to more microscopic aspects and other interests such as dc metamaterials (...
متن کاملSuperconductivity of ε-Fe: complete resistive transition
Last year, iron was reported to become superconducting at temperatures below 2K and pressures between 15 and 30 GPa [1]. The evidence presented was a weak resistivity drop, suppressed by a magnetic field above 0.2 T, and a small Meissner signal. However, a compelling demonstration, such as the occurrence of zero resistance, was lacking. Here we report the measurement of a complete resistive tra...
متن کاملSuperconductivity and magnetism in 11-structure iron chalcogenides in relation to the iron pnictides.
This is a review of the magnetism and superconductivity in '11'-type Fe chalcogenides, as compared to the Fe-pnictide materials. The chalcogenides show many differences from the pnictides, as might be anticipated from their very varied chemistries. These differences include stronger renormalizations that might imply stronger correlation effects as well as different magnetic ordering patterns. N...
