Selective coupling of coherent phonons to intertwined charge-orbital and magnetic orders in doped manganites
X. Liu, M. Sander, S. -W. Huang +15
Strongly correlated materials feature technologically relevant functionalities such as high-temperature superconductivity and colossal magnetoresistance, which emerges from the com…
Unveiling the nanomorphology of HfN thin films by ultrafast reciprocal space mapping
Steffen Peer Zeuschner, Jan-Etienne Pudell, Maximilian Mattern +5
Hafnium Nitride (HfN) is a promising and very robust alternative to gold for applications of nanoscale metals. Details of the nanomorphology related to variations in strain states…
Non-thermal electrons open the non-equilibrium pathway of the phase transition in FeRh
Maximilian Mattern, Steffen Peer Zeuschner, Matthias Rössle +3
We use ultrafast x-ray diffraction to study non-equilibrium pathways of the phase transition in FeRh parametrized by the structural response. By increasing the pump-pulse duration…
Accelerating the laser-induced phase transition in nanostructured FeRh via plasmonic absorption
Maximilian Mattern, Jan-Etienne Pudell, Jon Ander Arregi +5
By ultrafast x-ray diffraction we show that the laser-induced magnetostructural phase transition in FeRh nanoislands proceeds faster and more complete than in continuous films. We…
Speed limits of the laser-induced phase transition in FeRh
Maximilian Mattern, Jasmin Jarecki, Jon Ander Arregi +3
We use ultrafast x-ray diffraction (UXRD) and the polar time-resolved magneto-optical Kerr effect (tr-MOKE) to study the laser-induced metamagnetic phase transition in two FeRh fil…
Grueneisen-Approach for the Experimental Determination of Transient Spin and Phonon Energies from Ultrafast X-ray Diffraction Data: Gadolinium
A. Koc, M. Reinhardt, A. von Reppert +6
We study gadolinium thin films as a model system for ferromagnets with negative thermal expansion. Ultrashort laser pulses heat up the electronic subsystem and we follow the transi…
Ultrafast X-ray Diffraction Thermometry Measures the Influence of Spin Excitations on the Heat Transport through nanolayers
A. Koc, M. Reinhardt, A. von Reppert +5
We investigate the heat transport through a rare earth multilayer system composed of Yttrium (Y), Dysprosium (Dy) and Niobium (Nb) by ultrafast X-ray diffraction. This is an exampl…
Influence of La and Mn vacancies on the electronic and magnetic properties of LaMnO thin films grown by pulsed laser deposition
Ivan Marozau, Proloy T. Das, Max Döbeli +6
With pulsed laser deposition we have grown c-axis oriented thin films of the nominal composition LaMnO (LMO) on LSAT(001) substrates. We find that, depending on the oxygen ba…
Low-energy interband transitions in the infrared response of Ba(Fe1-xCox)2As2
P. Marsik, C. N. Wang, M. Roessle +8
We studied the doping and temperature (T) dependence of the infrared (IR) response of Ba(Fe1-xCox)2As2 single crystals. We show that a weak band around 1000 cm-1, that was previous…
Optical probe of ferroelectric order in bulk and thin film perovskite titanates
M. Rössle, C. N. Wang, P. Marsik +8
We have measured the temperature dependence of the direct band gap, , in SrTiO and BaTiO and related materials with quantum-paraelectric and ferroelectric prope…
Macroscopic phase segregation in superconducting K0.73Fe1.67Se2 as seen by muon spin rotation and infrared spectroscopy
C. N. Wang, P. Marsik, R. Schuster +8
Using muon spin rotation (\muSR) and infrared spectroscopy we investigated the recently discovered superconductor K0.73Fe1.67Se2 with Tc = 32 K. We show that the combined data can…
