Nanoscale Investigation of New Iron-Based Superconductors
We have successfully synthesized high quality β-FeSe-type iron chalcogenide nanowires (NWs) from annealing thin films prepared by pulse laser deposition method. Three kinds of NWs with nominal composition (FeSe0.9, FeSe0.3Te0.7 and FeTe0.8S0.2) have been prepared and carefully characterized by transmission electron microscope (TEM). Most analyzed NWs reveal good tetragonal structure along the (...
متن کاملQuasiparticle interference in iron-based superconductors
We systematically calculate quasiparticle interference QPI signatures for the whole phase diagram of iron-based superconductors. Impurities inherent in the sample together with ordered phases lead to distinct features in the QPI images that are believed to be measured in spectroscopic imaging-scanning tunneling microscopy. In the spin-density wave phase the rotational symmetry of the electronic...
متن کاملRadiation effects on iron-based superconductors
This article reviews the results of irradiation experiments on iron-based superconductors, with particular emphasis on neutron irradiation. These experiments were either done to foster the theoretical understanding of superconductivity in these compounds by investigating the influence of impurity scattering on the fundamental superconducting properties or to investigate vortex physics and to be...
متن کاملOptical conductivity of iron-based superconductors.
The new family of unconventional iron-based superconductors discovered in 2006 immediately relieved their copper-based high-temperature predecessors as the most actively studied superconducting compounds in the world. The experimental and theoretical effort made in order to unravel the mechanism of superconductivity in these materials has been overwhelming. Although our understanding of their m...
متن کاملARPES Results of ’122’ Iron-based Superconductors
The discovery of superconductivity in iron pnictides has attracted considerable interest of the condensed matter physics community [1]. The superconductivity has been observed in both 1111 and 122 system. These superconductors display a fascinating interplay between magnetism and superconductivity. Two kinds of techniques are mainly performed to study these materials. One is the neutron scatter...
