Impurity effect as a probe for order parameter symmetry in iron-based superconductors
The pointlike impurity scattering is studied for a superconductor with different pairing symmetries based on a minimal two band model proposed by S. Raghu et al. [Phys. Rev. B 77, R220503 (2008)], and the self-consistent Bogoliubov-de Gennes equations. Two intragap resonance peaks are found at or near the nonmagnetic impurity site for a typical sx2y2 symmetry and strong scattering potentials. S...
متن کاملTemperature Dependence Of Cuprate Superconductors’ Order Parameter
A model of charged hole-pair bosons, with long range Coulomb interactions and very weak interlayer coupling, is used to calculate the order parameter Φ of underdoped cuprates. Model parameters are extracted from experimental superfluid densities and plasma frequencies. The temperature dependence Φ(T ) is characterized by a ’trapezoidal’ shape. At low temperatures, it declines slowly due to harm...
متن کاملOne-Sign Order Parameter in Iron Based Superconductor
The onset of superconductivity at the transition temperature is marked by the onset of order, which is characterized by an energy gap. Most models of the iron-based superconductors find a sign-changing (s±) order parameter [1-6], with the physical implication that pairing is driven by spin fluctuations. Recent work, however, has indicated that LiFeAs has a simple isotropic order parameter [7-9]...
متن کاملStructure–property relationships of iron arsenide superconductors
Iron based superconductors sent material scientists into a renewed excitement reminiscent of the time when the first high-Tc superconductors were discovered 25 years ago. This feature article reviews relationships between structural chemistry and magnetic as well as superconducting properties of iron arsenide compounds, which are outstandingly rich and uniquely coupled. Particular attention is ...
متن کاملFluctuation Effects And Order Parameter Symmetry In The Cuprate Superconductors
Effect of phase fluctuations on superconducting states with anisotropic order parameters is studied in a BCS like lattice model of cuprate superconductors. The degradation of the mean field transition temperature due to phase fluctuations is estimated within a Kosterlitz-Thouless scenario. Values of the interaction parameters for optimal doping, corresponding to a stable superconducting state o...
