Andrej Farkaš, Institute of Physics of the Czech Academy of Sciences (Czech Republic) and Charles Univ. (Czech Republic); Miloslav Surýnek, Charles Univ. (Czech Republic); Filip Křížek, Vít Novák, Institute of Physics of the Czech Academy of Sciences (Czech Republic); Petr Němec, Charles Univ. (Czech Republic); Kamil Olejník, Institute of Physics of the Czech Academy of Sciences (Czech Republic)
Antiferromagnetic (AF) materials are gaining interest in spintronics due to their absence of net magnetization, high integration potential, and ultrafast dynamics compared to ferromagnets. Quench-switching in CuMnAs, a heat-induced effect using electrical or optical stimuli, relies on domain structure changes near the Néel temperature. This study examines laser pulse parameters affecting switching in CuMnAs films.

Michal Hubert, Tomáš Maleček, Charles Univ. (Czech Republic); Dominik Kriegner, Karel Výborný, Institute of Physics of the Czech Academy of Sciences (Czech Republic); Martin Veis, Charles Univ. (Czech Republic)
Antiferromagnets are promising materials for spintronic memory applications. Hexagonal manganese telluride belongs to a class of collinear antiferromagnets exhibiting non-relativistic spin splitting in its electronic band structure. Following the recent observation of anomalous Hall effect in MnTe, this work reports the hysteresis measurement of the magneto-optical Kerr effect.

Optically-induced magnetic dynamics in altermagnetic candidate MnTe
J. Střihavková, J. Kimák, Z. Sadeghi, Charles Univ. (Czech Republic); D. Kriegner, H. Reichlová, Institute of Physics of the Czech Academy of Sciences (Czech Republic) and Technical Univ. Dresden (Germany); G. Springholz, Johannes Kepler Univ. Linz (Austria): E. Schmoranzerová, P. Němec, Charles Univ. (Czech Republic)
Altermagnets, materials with antiparallel ordering of magnetic moments and a spin-split electronic band structure, are promising candidates for spintronic applications. We have investigated magnetic dynamics of the thin-film altermagnetic candidate MnTe using time-resolved magnetooptics, observing the magnetooptical effect in two regions, which indicate different orientations of the Néel vector.

Optical and magneto-optical spectroscopies of half- and full-Heusler Rh-Mn-Sb thin films

Heusler compounds are highly valued for their tunable electronic structure and exceptional magneto-optical properties, making them ideal for spintronics and other applications. We studied magneto-optical spectroscopy and ellipsometry on Rh2MnSb and RhMnSb thin films. Results revealed large magneto-optical responses, in-plane magnetic anisotropy, and differences in manganese d-orbital contributions between full- and half-Heusler structures.
12:05 - 12:25
Large magneto-optical response of Eu0.5Bi2.5Fe5O12 thin garnet films prepared by metal-organic decomposition

Ferrimagnetic iron garnets, such as Eu0.5Bi2.5Fe5O12, are promising for magneto-optical and spintronic applications. Thin films prepared via metal-organic decomposition exhibited large Faraday rotation, exceeding 7.5° at 2.9 eV for 50 nm thickness. Hysteresis loops revealed strong out-of-plane anisotropy, likely due to Eu doping or substrate-induced strain.

Ultrafast spectroscopy of single light-harvesting complexes
May Myat Noe Shein, Pavel Malý, Charles Univ. (Czech Republic)
Ultrafast spectroscopy with single-molecule fluorescence reveals excitation dynamics in complex systems like photosynthetic complexes. Using a time-resolved fluorescence microscope, we track the excitation spectra, fluorescence lifetimes, and transient spectra at the level of individual complexes. This novel approach uncovers mechanisms hidden by ensemble averaging in disordered systems, with initial results demonstrating its potential.

Evangelos Ofreas Efraimidis, Barbora Špačková, Tereza Roesel Institute of Physics of the Czech Academy of Sciences (Czech Republic); Niklas Hansen, Vladimíra Petráková, J. Heyrovský Institute of Physical Chemistry of the Czech Academy of Sciences (Czech Republic)
Nanofluidic Scattering Microscopy (NSM) enables real-time imaging of biomolecules in solution, determining molecular weight via optical contrast and polarizability. NSM allows native-state analysis, overcoming limitations of traditional mass spectrometry. By integrating single-molecule manipulation with advanced data processing, NSM achieves high-resolution molecular weight measurement with potential for atomic-level resolution, unlocking new possibilities for studying biomolecular interactions and dynamics.

Analyzing transparent materials like low-density gas jets challenges sensitivity limits. We present a multi-pass optical probing technique, boosting phase sensitivity and enabling detailed visualization of structures like shocks. Using wavefront sensor, we reconstruct 3D gas density distributions, advancing applications in laser wakefield acceleration and compact X-ray sources.

Bayesian optimization for ultrafast X-ray generation from dual-stage laser-plasma accelerators

(Czech Republic); Uddhab Chaulagain, ELI Beamlines, ELI ERIC (Czech Republic), Jaroslav Nejdl, ELI Beamlines, ELI ERIC (Czech Republic) and Czech Technical Univ. in Prague (Czech Republic); Marcel Lamač, ELI Beamlines, ELI ERIC (Czech Republic)
Laser wakefield acceleration (LWFA) has proven effective in producing high-energy electron beams, which generate bright X-ray pulses through betatron oscillations. We demonstrate how Bayesian optimisation can optimise the parameters of passive plasma lensing, a multi-jet scheme used to increase the magnitude of X-ray radiation, using particle-in-cell (PIC) simulations.

Resonant betatron X-ray generation using chirped laser pulses
Orsolya Morvai, ELI Beamlines, ELI ERIC (Czech Republic) and Charles Univ.

Bulanov, Marcel Lamač, ELI Beamlines, ELI ERIC (Czech Republic)
Laser wakefield acceleration (LWFA) is an advanced technique for compact electron acceleration and X-ray generation. However, insufficient photon flux remains a challenge. In this study, we examine the effect of chirped laser pulses on betatron X-ray generation, focusing on how variations in chirp parameters influence the transverse momentum of electrons, as well as the energy and flux of the emitted X-rays. Introducing a chirp modifies wakefield evolution without altering pulse energy, potentially increasing the charge and energy of the accelerated electrons. These insights aim to enhance control over future LWFA and betatron experiments.

Plasmon-enhanced fluorescence imaging biosensor for single molecule detection
Katharina Schmidt, Naoto Asai, Danube Private Univ. (Austria); Gizem Aktug, Institute of Physics of the Czech Academy of Sciences (Czech Republic); Jakub Dostalek, Danube Private Univ. (Austria) and Institute of Physics of the Czech Academy of Sciences (Czech Republic)
We report on an ultrasensitive biosensor advanced for protein biomarker detection in real-world samples. The Rolling circle amplification (RCA) serves as an enzymatic based enhancement technique. It is based on a circular probe binding to a primer sequence for prolongation, leading to long single-stranded DNA. It serves as a scaffold to either subsequently bind fluorophore-tagged labelling strands or provide the possibility to incorporate fluorophores during the amplification process. The real-time labelling is monitored by a combined surface plasmon resonance and plasmon-enhanced fluorescence (PEF) set-up. Additionally, a home-built PEF imaging device was developed for single-molecule resolution.

We present a high-performance affinity plasmonic biosensor based on arrays of gold nanoparticles. By replacing metallic adhesion layers with non-damping molecular linkers, we achieved enhanced plasmonic properties. Additionally, the use of antifouling functional coatings significantly increased biomolecular detection sensitivity. Improved fabrication techniques ensured facile and reproducible sensor production.
