Sb-5-mediated antiparallel Nd-Fe coupling in NdFeSb
S. Palazzese, Sh. Yamamoto, T. Kotte +15
We uncover the microscopic mechanism underlying the antiparallel Nd-Fe coupling in the intermetallic 4-3-5 compound NdFeSb by means of high-field x-ray magneti…
Electric field switching of chiral phonons
Michael Grimes, Clifford J. Allington, Hiroki Ueda +8
Lattice vibrations carrying angular momentum, known as chiral phonons, have emerged as a promising route to control and understand complex material properties, yet their determinis…
Ligand Mediated Magnetic Coupling Across Metamagnetic Transitions in CrPS4
Giuseppe Buccoliero, Rachel Nickel, Roberto Sant +8
Chromium thiophosphate (CrPS4) is a long-known material: a layered semiconducting antiferromagnet. Its recently discovered gate-tunable metamagnetic phase transitions, the remarkab…
X-raying Mg0.2Co0.2Ni0.2Cu0.2Zn0.2O: disentangling elemental contributions in a prototypical high-entropy oxide
Maryia Zinouyeva, Martina Fracchia, Giulia Maranini +10
We employ several X-ray based techniques, including X-ray diffraction, absorption and resonant inelastic scattering, to disentangle the contributions of individual chemical species…
Temperature dependent Resonant X-ray Inelastic Scattering at Ni L3-edge for NaNiO2 and LiNiO2
Quentin Jacquet, Kurt Kummer, Marie Guignard +4
LiNiO2 is a promising cathode material for Li-ion battery but its atomic and electronic structure is under debate. Indeed, two sets of Ni-O distances are identified from local stru…
Chiral Altermagnon in MnTe
Daniel Jost, Resham B. Regmi, Eder G. Lomeli +12
Altermagnetism has surfaced as a novel magnetic phase, bridging the properties of ferro- and anti-ferromagnetism. The momentum-dependent spin-splitting observed in these materials…
Controlling 4f antiferromagnetic dynamics via itinerant electronic susceptibility
Sang-Eun Lee, Yoav William Windsor, Daniela Zahn +10
Optical manipulation of magnetism holds promise for future ultrafast spintronics, especially with lanthanides and their huge, localized 4f magnetic moments. These moments interact…
Voltage-driven 90 switching of bulk perpendicular magnetic anisotropy in ferrimagnets
Zhengyu Xiao, Ruiwen Xie, Fernando Maccari +18
Unravelling the mechanism behind bulk perpendicular magnetic anisotropy (PMA) in amorphous rare earth-transition metal films has proven challenging. This is largely due to the inhe…
A full gap above the Fermi level: the charge density wave of monolayer VS2
Camiel van Efferen, Jan Berges, Joshua Hall +15
In the standard model of charge density wave (CDW) transitions, the displacement along a single phonon mode lowers the total electronic energy by creating a gap at the Fermi level,…
Microscopic effects of Dy-doping in the topological insulator Bi2Te3
L. B. Duffy, N. -J. Steinke, J. A. Krieger +13
Magnetic doping with transition metal ions is the most widely used approach to break timereversal symmetry in a topological insulator, a prerequisite for unlocking the TIs exotic p…
Structure, site-specific magnetism and magneto-transport properties of epitaxial D0 MnFeGa thin films
Davide Betto, Yong-Chang Lau, Kiril Borisov +5
Ferrimagnetic MnFeGa thin films have been characterised by X-ray diffraction, SQUID magnetometry, X-ray absorption spectroscopy, X-ray magnetic ci…
Using a dual plasma process to produce cobalt--polypyrrole catalysts for the oxygen reduction reaction in fuel cells -- part II: analysing the chemical structure of the films
Christian Walter, Kurt Kummer, Denis Vyalikh +3
The chemical structure of cobalt--polypyrrole -- produced by a dual plasma process -- is analysed by means of X-ray photoelectron spectroscopy (XPS), near edge X-ray absorption spe…
Dynamics of graphene growth on a metal surface: a time-dependent photoemission study
Alexander Grüneis, Kurt Kummer, Denis V. Vyalikh
Applying time-dependent photoemission we unravel the graphene growth process on a metallic surface by chemical vapor deposition (CVD). Graphene CVD growth is in stark contrast to t…
