Filming the formation and fluctuation of skyrmion domains by cryo-Lorentz transmission electron microscopy

Henrik Moodysson Rønnow, Arnaud Magrez, Fabrizio Carbone, Marco Cantoni, Jonathan White, Edoardo Baldini, Giulia Fulvia Mancini, Tatiana Latychevskaia, Ping Huang, Yoshie Murooka, Rajeswari Jayaraman

Magnetic skyrmions are promising candidates as information carriers in logic or storage devices thanks to their robustness, guaranteed by the topological protection, and their nanometric size. Currently, little is known about the influence of parameters su ...

A setup for hard x-ray time-resolved resonant inelastic x-ray scattering at SwissFEL

Majed Chergui, Giulia Fulvia Mancini, Michele Puppin, Ludmila Maria Diniz Leroy, Hui-Yuan Chen, Rolf Baldwin Versteeg

We present a new setup for resonant inelastic hard x-ray scattering at the Bernina beamline of SwissFEL with energy, momentum, and temporal resolution. The compact R = 0.5 m Johann-type spectrometer can be equipped with up to three crystal analyzers and al ...

Towards X-ray transient grating spectroscopy

Patrice Beaud, Majed Chergui, Giulia Fulvia Mancini, Jérémy Raymond Jean Maurice Rouxel, Erwan Fabrice Koch

The extension of transient grating spectroscopy to the x-ray regime will create numerous opportunities, ranging from the study of thermal transport in the ballistic regime to charge, spin, and energy transfer processes with atomic spatial and femtosecond t ...

Femtosecond X-ray spectroscopy of haem proteins

Majed Chergui, Giulia Fulvia Mancini, Oliviero Cannelli, Dominik Kinschel, Camila Bacellar Cases Da Silveira, Boris Sorokin

We discuss our recently reported femtosecond (fs) X-ray emission spectroscopy results on the ligand dissociation and recombination in nitrosylmyoglobin (MbNO) in the context of previous studies on ferrous haem proteins. We also present a preliminary accoun ...

Ultrafast Energy Transfer from Photoexcited Tryptophan to the Haem in Cytochrome c

Majed Chergui, Giulia Fulvia Mancini, Oliviero Cannelli, Dominik Kinschel, Camila Bacellar Cases Da Silveira, Jérémy Raymond Jean Maurice Rouxel, Yang Zhao, Rebecca Ann Ingle

: We report femtosecond Fe K-edge absorption (XAS) and nonresonant X-ray emission (XES) spectra of ferric cytochrome C (Cyt c) upon excitation of the haem (>300 nm) or mixed excitation of the haem and tryptophan (

Tabletop EUV Coherent Diffractive Imaging and Small Angle Scattering of Colloidal Crystals

Giulia Fulvia Mancini

We demonstrate full-field quantitative ptychographic imaging using tabletop high harmonics to visualize the extended structure of silica close-packed nanosphere multilayers with

Direct observation of photo-mechanical stiffness in alkanethiol-capped gold nanoparticles supracrystals by ultrafast small-angle electron diffraction

Francesco Stellacci, Fabrizio Carbone, Giulia Fulvia Mancini, Tatiana Latychevskaia, Javier Reguera Gomez, Francesco Pennacchio

We demonstrate that ultrastiff bonding between nanoparticles can be engineered by ad hoc assemblies of ligands, reaching strengths comparable to that of strong covalent bonds. Our observation relies on femtosecond small-angle electron diffraction. ...

Hard X-ray transient grating spectroscopy on bismuth germanate

Majed Chergui, Giulia Fulvia Mancini, Jérémy Raymond Jean Maurice Rouxel

Optical-domain transient grating (TG) spectroscopy is a versatile background-free four-wave-mixing technique that is used to probe vibrational, magnetic and electronic degrees of freedom in the time domain(1). The newly developed coherent X-ray free-electr ...
