Laser induced ultrafast Co 3d and Ho 4f spin dynamics in CoHo ferrimagnetic alloys
Deeksha Gupta, Boonthum Kunyangyuen, Matthias Riepp +8
The transition metal (TM) / rare-earth (RE) alloys have received renewed interest lately as model systems to decipher the origin of all-optical helicity-independent switching (AO-H…
Tuning of the ultrafast demagnetization by ultrashort spin polarized currents in multi-sublattice ferrimagnets
Deeksha Gupta, Maryna Pankratova, Matthias Riepp +11
Femtosecond laser pulses can be used to induce ultrafast changes of the magnetization in magnetic materials. Several microscopic mechanisms have been proposed to explain the observ…
Direct observation of Néel-type skyrmions and domain walls in a ferrimagnetic DyCo thin film
Chen Luo, Kai Chen, Victor Ukleev +5
Isolated magnetic skyrmions are stable, topologically protected spin textures that are at the forefront of research interests today due to their potential applications in informati…
Inner relaxations in equiatomic single-phase high-entropy cantor alloy
Alevtina Smekhova, Alexei Kuzmin, Konrad Siemensmeyer +6
The superior properties of high-entropy multi-functional materials are strongly connected with their atomic heterogeneity through many different local atomic interactions. The deta…
Chiral surface spin textures in CuOSeO unveiled by soft x-ray scattering in specular reflection geometry
V. Ukleev, C. Luo, R. Abrudan +3
Resonant elastic soft x-ray magnetic scattering (XRMS) is a powerful tool to explore long-periodic spin textures in single crystals. However, due to the limited momentum transfer r…
Laser induced ultrafast Gd 4f spin dynamics in Co100-xGdx alloys by means of time-resolved XMCD
T. Ferté, M. Beens, G. Malinowski +8
We have studied the laser induced ultrafast quenching of Gd 4f magnetic order in ferrimagnetic Co100-xGdx alloys to highlight the role of the inter-atomic exchange coupling. We hav…

Boris Seng, Daniel Schönke, Javier Yeste +15
The evolution of chiral spin structures is studied in ferrimagnet Ta/Ir/Fe/GdFeCo/Pt multilayers as a function of temperature using scanning electron microscopy with polarization a…
Charge transfer induced interfacial ferromagnetism in LaSrMnO/NdNiO
K. Chen, C. Luo, B. B. Chen +4
Charge transfer induced interfacial ferromagnetism and its impact on the exchange bias effect in LaSrMnO/NdNiO correlated oxide heterostructures were invest…
Giant topological Hall effect in correlated oxide thin films
Lorenzo Vistoli, Wenbo Wang, Anke Sander +15
Strong electronic correlations can produce remarkable phenomena such as metal-insulator transitions and greatly enhance superconductivity, thermoelectricity, or optical non-lineari…
Ultrafast hot-electron induced quenching of Tb4f magnetic order
T. Ferte, N. Bergeard, G. Malinowski +5
We have investigated ultrafast quenching of the Tb4f magnetic order in Co74Tb26 alloys, induced by femtosecond hot-electrons pulses. The hot-electron pulses were produced in specif…
Enhanced and Tunable Spin-Orbit Coupling in Tetragonally Strained Fe-Co-B Films
Ruslan Salikhov, Ludwig Reichel, Benjamin Zingsem +8
We have synthesized 20 nm thick films of tetragonally strained interstitial Fe-Co-B alloys epitaxially grown on Au55Cu45 buffer layer. The strained axis is perpendicular to the fil…
