Faster chiral versus collinear magnetic order recovery after optical excitation revealed by femtosecond XUV scattering
Nico Kerber, Dmitriy Ksenzov, Frank Freimuth +11
While chiral spin structures stabilized by Dzyaloshinskii-Moriya interaction (DMI) are candidates as novel information carriers, their dynamics on the fs-ps timescale is little kno…
Ultrafast negative thermal expansion driven by spin-disorder
J. Pudell, A. von Reppert, D. Schick +5
We measure the transient strain profile in a nanoscale multilayer system composed of Yttrium, Holmium and Niobium after laser excitation using ultrafast X-ray diffraction. The stra…
Ultrafast and Energy-Efficient Quenching of Spin Order: Antiferromagnetism Beats Ferromagnetism
Nele Thielemann-Kühn, Daniel Schick, Niko Pontius +6
By comparing femtosecond laser pulse induced ferro- and antiferromagnetic dynamics in one and the same material - metallic dysprosium - we show both to behave fundamentally differe…
The effect of interface roughness on exchange bias in La0.7Sr0.3MnO3 - BiFeO3 heterostructures
Mehran Vafaee, Simone Finizio, Hakan Deniz +4
We characterized the interfaces of heterostructures with different stack sequences of La0.7Sr0.3MnO3/BiFeO3 (LSMO/BFO) and BFO/LSMO using TEM revealing sharp and rough interfaces,…
Itinerant and localized magnetization dynamics in antiferromagnetic Ho
L. Rettig, C. Dornes, N. Thielemann-Kuehn +12
Using femtosecond time-resolved resonant magnetic x-ray diffraction at the Ho L3 absorption edge, we investigate the demagnetization dynamics in antiferromagnetically ordered metal…
Growth modes of nanoparticle superlattice thin films
D. Mishra, D. Greving, G. A. Badini Confalonieri +4
We report about the fabrication and characterization of iron oxide nanoparticle thin film superlattices. The formation into different film morphologies is controlled by tuning the…
