Superconductivity, magnetism, and spin fluctuations in Fe-based superconductorsSince the discovery of a high temperature superconducting transition in ferropnictides approximately two years ago, the highly magnetic character of these compounds and the close relationship between superconductivity and magnetism has been widely recognized and intensely studied. Initially, debate about … Continue reading |

NMR in pnictidesWe will first present the basic principles and the uses of Nuclear Magnetic Resonance in Solid State Physics and especially in strongly correlated materials based on a few examples. NMR is a local probe which enables to get unique informations … Continue reading |

Novel tetragonal antiferromagnetic phase in Ba(Fe$_{1-x}$Mn$_x$)$_2$As$_2$In 122-ferropnictides, superconductivity can be induced either by iso- or aliovalent chemical substitution or by applying a mechanical pressure to the antiferromagnetic parent compounds. In particular, one can introduce extra electrons or holes into the FeAs layers by replacing Fe … Continue reading |

Probing The Local Magnetic Structure Of A Quasi-1D Cuprate With Resonant Inelastic X-ray ScatteringThe quasi-one-dimensional cuprate Li$_2$CuO$_2$ is a prototype edge-sharing chain compound [1]. The Cu$^{2+}$ ions in this strongly correlated material give rise to one spin ½ per CuO$_4$ plaquette with a nearest neighbor Cu-O-Cu bond angle close to 90° implying weak … Continue reading |

T_c in pnictides and cuprates correlates with the electron-phonon relaxation timesThe pairing mechanism in high critical temperature (T_c) superconductors is one of the outstanding mysteries of condensed matter physics. Here we show that for cuprates and pnictides both electron-phonon interaction (EPI) and electron-electron interaction (EEI) are necessary ingredients. To investigate … Continue reading |

Low energy kink in the cuprates and effective interaction for systems with competing electron-electron and electron-phonon couplingMotivated by the observation in the copper-oxide high-temperature superconductors, we investigate the appearance of kinks in the electronic dispersion due to coupling to phonons in the presence of a strong electronic repulsion. To model this strong coupling situation we present … Continue reading |
