Shedding Light on Iron-Chalcogenide/Pnictide Superconductors by Inelastic Scattering
Date: Friday July 22, 2011
Time: 12:00 pm – 1:00 pm
Location: Houston Science Center – Building 593 — Room 102
Overview
Iron-based superconductors are materials with many intriguing properties as competing magnetic and superconducting orders, non-phonon mediated pairing mechanism, direct substitutional doping into the active pairing layer, and metallic multiband nature of the parent compounds. Although there is no a “silver bullet” approach to such a complexity, the light scattering techniques have proven to be a useful tool for studying these superconductors. Inelastic scattering of light from solids is commonly known as Raman scattering by phonons. The scattering process, however, always proceeds through electrons and can also involve a broad range of elementary excitations as intra-ionic electronic transitions (crystal-field excitations), intra and inter-band electronic transitions, magnons through spin-orbit coupling, and electronic pair-breaking excitations in superconductors. I will address the achievements, challenges, and perspectives in studying iron chalcogenides and pnictides by a combined experimental Raman scattering and first-principles simulation approach.
