37. The SwissFEL X-ray Laser and its Applications in Correlated Electron Materials

Rafael Abela (PSI)

Invited talk

Beginning in the year 2017, the SwissFEL X-ray laser at the Paul Scherrer Institut will provide users with ultra-bright, 20 femtosecond pulses of X-rays, with photon energies 180 – 12’400 eV, with a high degree of transverse coherence and at a repetition rate of 100 Hz. Shortly later, the performance will be extended to include simultaneous operation of two beamlines, circular polarization,...

Talk

Electronic orderings in correlated systems can compete and/or cooperate with electron itinerancy and lead to the emergence phenomena like colossal magnetoresistance (CMR) and high temperature superconductivity (HTSC). To understand how these orderings can show up from strong correlations, resonant soft X-ray scattering (RSXS) spectroscopy has been demonstrated as one of the most powerful...

23. The Verwey transition ultrafast: lattice and charge/orbital order go neck and neck

Talk

At 120K magnetite Fe3O4 undergoes a metal-to-insulator transition, the Verwey transition. It is accompanied by a transition from a charge/orbital ordered state with a monoclinic symmetry to a high temperature cubic phase without electronic order. Until today the question whether this transition is mainly driven by the lattice or by electronic degrees of freedom remains unanswered. We...
