Femtosecond Spectroscopy and X-ray Spectroscopy Group


The Femtosecond Spectroscopy and X-ray Spectroscopy Group has been applying spectroscopy techniques based on synchrotron radiation, aiming to study electronic bistability and metastable excited states in transition metal compounds, as well as the electronic structure of oxides with correlated electrons. Recently, our main activity shifted to applying X-ray spectroscopy as probes to study ultrafast structural and electronic dynamics in pump-probe experiments, with ps and fs resolution. This research is complemented by theoretical and femtosecond laser studies in our institute. We have realized a transient optical absorption setup, and we are currently building a time-resolved fluorescence and a stimulated Raman scattering setup. The research opportunities offered by our complementary laser, X-ray and theory programme allows us to efficiently tackle ultrafast dynamics of molecular systems in the condensed phase.

The most relevant part of our research is done at synchrotron radiation facilities and X-ray free electron lasers. Current research topics include studying transition metal oxides with correlated electrons, switchable metal complexes, and ultrafast transitions applying X-ray spectroscopy.

Using ERC support, we have built a laboratory to develop X-ray optics and X-ray spectroscopy. With the Lendület grant of the HAS, we have realized a pump-probe setup in the then HELIOS lab of the Wigner RCP, which allows us to record transient optical absorption with femtosecond time resolution. With the help of the running grants from the national excellency programmes VEKOP and NKP, we are realizing further instrumentation for time-resolved probes, including fluorescence and stimulated Raman scattering.
From these fundings we have also built up a computer cluster to carry out quantum chemistry and dynamics calculations.

Our group shares a Mössbauer spectroscopy laboratory with the Functional Nanostructures Group. This laboratory is equipped with several spectrometers, of which we mostly use the ones dedicated to emission Mössbauer spectroscopy studies (MES). We run a chemistry laboratory and two isotope laboratories. We have access to other facilities on the KFKI campus through several collaborations with other groups.

HIGHLIGHTS
Laboratory X-ray absorption spectroscopy
A new, easily operated high resolution von Hámos type X-ray spectrometer has been developed, which offers rapid transmission experiments for X-ray absorption on concentrated (routine) samples in the laboratory, replacing the need for synchrotron studies. We demonstrated the proof of principle and give examples for applications in solids and in solutions.

Insights into the function of a light-harvesting model system
Ultrafast photoinduced electron transfer preceding energy equilibration still poses many experimental and conceptual challenges to the optimization of photoconversion since an atomic-scale description has so far been beyond reach. Here we combine femtosecond transient optical absorption spectroscopy with ultrafast X-ray emission spectroscopy and diffuse X-ray scattering at the SACLA facility to track the non-equilibrated electronic and structural dynamics within a bimetallic donor–acceptor complex that contains an optically dark centre. Exploiting the 100-fold increase in temporal resolution as compared with storage ring facilities, these measurements constitute the first X-ray-based visualization of a non-equilibrated intramolecular electron transfer process over large interatomic distances. Experimental and theoretical results establish that mediation through electronically excited molecular states is a key mechanistic feature. The present study demonstrates the extensive potential of femtosecond X-ray techniques as diagnostics of non-adiabatic electron transfer processes in synthetic and biological systems, and some directions for future studies, are outlined.

Tracking excited-state charge and spin dynamics in iron coordination complexes
Photo-induced spin-state transition of molecular compounds of iron has great potential for applications in molecular devices. The low to high spin excitation in Fe(II) compounds involves flipping two electron spins in less than 300 femtosecond. Therefore, the detailed mechanism of the ultrafast spin switching has been ill-understood due to the lack of proper tools to provide insights in the ultrashort time window. We have managed to close this knowledge gap exploiting the spin momentum sensitivity of X-ray emission spectroscopy at the Linac Coherent Light Source, the first hard X-ray free electron laser (at the Stanford Linear Accelerator Center, USA), in a pioneering experiment using 100 femtosecond time resolution. We were able to determine the de-excitation sequence for a benchmark Fe(II) molecule showing a singlet to quintet transition, establishing the critical role of intermediate triplet spin states in the transition mechanism.

On the microscopic origin of the nanoscale magnetic-electronic phase separation in LSCO
Investigating the roots of a nanoscale magneto-electronic phase separation (responsible for their magnetoresistance as well as cooperative electric and magnetic phase transitions) in bulk Sr-doped LaCoO3 (LSCO), we have combined local spectroscopic techniques as synchrotron XES and laboratory Mössbauer spectroscopy to identify and characterize the clusterization process. A simple model based on the random distribution of the doping Sr ions describes well both the doping-driven evolution of the separated phases and the variation of the Co spin state.
