Collective Magnetic Excitations in a Photo-excited Electron-doped Cuprate Superconductor
Daniel Jost, Jiarui Li, Jordyn Hales +21
Elucidating the microscopic behavior of cuprates under ultrafast photoexcitation offers critical insights into their highly correlated out-of-equilibrium states. Although quasipart…
Photo-generated charge-transfer excitons in NiO revealed by ultrafast time-resolved resonant inelastic x-ray scattering
Giacomo Merzoni, Leonardo Martinelli, Sergii Parchenko +32
Strong electronic correlation can lead to insulating behavior and to the opening of large optical gaps, even in materials with partly filled valence shells. Although the non-equili…
Demagnetization dynamics after noncollinear dual optical excitation
Sergii Parchenko, Matthias Riepp, Simon Marotzke +4
We explore the impact of optical excitation using two interfering ultrashort optical pulses on ultrafast magnetization dynamics. Our investigation focuses on Pt/Co/Pt multilayers a…
The Heisenberg-RIXS instrument at the European XFEL
Justine Schlappa, Giacomo Ghiringhelli, Benjamin E. Van Kuiken +44
Resonant Inelastic X-ray Scattering (RIXS) is an ideal X-ray spectroscopy method to push the combination of energy and time resolutions to the Fourier transform ultimate limit, bec…
Optically Induced Ferromagnetic Order in a Ferrimagnet
Sergii Parchenko, Agne Åberg Larsson, Vassilios Kapaklis +2
The parallel or antiparallel arrangement of electron spins plays a pivotal role in determining the properties of a physical system. To meet the demands for innovative technological…
Plasmon-enhanced optical control of magnetism at the nanoscale via the inverse Faraday effect
Sergii Parchenko, Kevin Hofhuis, Agne Ciuciulkaite +4
The relationship between magnetization and light has been the subject of intensive research for the past century, focusing on the impact of magnetic moments on light polarization.…
Magnetization precession after non-collinear dual optical excitation
Sergii Parchenko, Davide Pecchio, Ritwik Mondal +2
We investigate the impact of non-collinear dual optical excitation on the magnetization precession in a permalloy thin film using two ultrashort laser pulses. By analyzing the magn…
Transient non-collinear magnetic state for all-optical magnetization switching
Sergii Parchenko, Antoni Frej, Hiroki Ueda +12
Resonant absorption of a photon by bound electrons in a solid can promote an electron to another orbital state or transfer it to a neighboring atomic site. Such a transition in a m…
Giant magnetic anisotropy in the atomically thin van der Waals antiferromagnet FePS3
Youjin Lee, Suhan Son, Chaebin Kim +13
Van der Waals (vdW) magnets are an ideal platform for tailoring two-dimensional (2D) magnetism with immense potential for spintronics applications and are intensively investigated.…
Direct observation of a dynamical glass transition in a nanomagnetic artificial Hopfield network
Michael Saccone, Francesco Caravelli, Kevin Hofhuis +7
Spin glasses, generally defined as disordered systems with randomized competing interactions, are a widely investigated complex system. Theoretical models describing spin glasses a…
Magnetic and all-optical switching properties of amorphous TbCo alloys
Agne Ciuciulkaite, Kshiti Mishra, Marcos V. Moro +12
Amorphous TbCo magnetic alloys exhibit a list of intriguing properties, such as perpendicular magnetic anisotropy, high magneto-optical activity and magnetization s…
