Gap-modulation infrared spectroscopy of high transition temperature superconductors.
Conventional methods of determining the coupling factor alpha(2)(omega)F(omega) for the newly discovered high transition temperature (T(c)) cuprate superconductors by using tunneling and infrared measurements have thus far failed to show the cause of the very high T(c) of these compounds. This is due in part to difficulties in sample preparation for tunneling studies and to difficulties in obta...

Root of a Carbon nanotube on the sub-strate with elongated catalyst particle Rolled up AlGaAs/Cr/Pt microtube Corrosion pit generated on a shot-peened Zr-based bulk metallic glass Lattice structure of a typical edge-shared chain cuprate: Li 2 CuO 2 In February 2008, a paper appeared showing superconductivity in a layered iron arse-nide material with a transition temperature (T c) of 26K[1]. Thi...
متن کاملMagnetism and its microscopic origin in iron-based high-temperature superconductors
High-temperature superconductivity in the iron-based materials emerges from, or sometimes coexists with, their metallic or insulating parent compound states. This is surprising, as these undoped states exhibit dramatically different antiferromagnetic spin arrangements and Néel temperatures. Although there is a general consensus that magnetic interactions are important for superconductivity, muc...
متن کاملSpectroscopic Studies of Quasiparticle Low-Energy Excitations in Cuprate and Iron-Based High-Temperature Superconductors
Recent development in the physics of high-temperature superconductivity is reviewed, with special emphasis on the studies of the low-energy excitations of cuprate and iron-based superconductors. For cuprate superconductors, a phenomenology based on coexisting competing orders with superconductivity in the ground state of these doped Mott insulators is shown to provide a consistent account for a...
متن کاملTransition temperature and a spatial dependence of the superconducting gap for multilayer high-temperature superconductors.
We derive the expressions for the transition temperature (Tc), and the spatial dependence of the superconducting gap for a multilayer high-Tc superconductor composed of groups of tightly spaced planes separated by a larger distance. The results are compared with experiment and provide a strong support for an interlayer hopping as the driving force of the large Tc enhancement in multilayered com...
