  1. 72. Local moments in iron-based superconductors

    Invited Speaker / Conférencier invité
    Understanding magnetism in iron-based superconductors presents a difficult challenge facing researchers in this field. While a local spin model seems to describe a large subset of experimental data, these compounds are distinctly metallic and the itinerancy of electrons must be crucial for magnetism. Recent studies have suggested that both local and itinerant nature could be in play, since...

  2. 180. Sudden reversal in the pressure dependence of Tc in the iron-based superconductor CsFe2As2: A possible link between inelastic scattering and pairing symmetry

    We report a sudden reversal in the pressure dependence of Tc in the iron-based superconductor CsFe2As2, similar to that discovered recently in KFe2As2. As in KFe2As2, we observe no change in the Hall coefficient at T=0, again ruling out a Lifshitz transition across the critical pressure Pc. We interpret the Tc reversal in the two materials as a phase transition from one pairing state to...

  3. 178. Shedding new light on the phase diagram of cuprate superconductors
    Dr Olivier Cyr-Choinière (Université de Sherbrooke)

    Condensed Matter and Materials Physics / Physique de la matière condensée et matériaux (DCMMP-DPMCM)
    Invited Speaker / Conférencier invité
    In 1986, condensed-matter physics was profoundly shaken by the discovery of high-temperature superconductivity in materials known as cuprates. With a transition temperature *Tc* above liquid nitrogen temperature, these materials quickly proved to be promising for technological applications. However, the major motivation for the scientific community has been to understand the fundamental...
