2021-05-31: Theory predicts Magnetic Nutation Waves
In our recent publication on "Dispersion relation of nutation surface spin waves in ferromagnets" we predict the existence a new type of spin wave with surprising high frequency properties. This finding may become of importance for the development of novel magnonic information processors at THz frequencies. Contact: anna.semisalova@uni-due.de
2021-05-31: Au/Fe nanoparticles for magnetoplasmonics
in an international collaboration we could demonstrate the synthesis of solid solution fcc AuFe nanoparticles in ambient conditions by an adapted method previously established for a Fe3O4-Au core-shell morphology. The metastable paramagnetic AuFe particles segregate into Janus Au/Fe particles with bcc Fe and fcc Au upon annealing. The results deliver a new material with perspectives in magnetoplasmonics and biomedicine and suggest the reconsideration of existing protocols on magnetite-gold core-shell synthesis.

2020-10-07: DAAD funded research stay of scientists from Russia
We welcome in our group Dr. Natalia Shkodich (Merzhanov Institute of Structural Macrokinetics and Materials Science, Russian Academy of Sciences) and Dr. Mikhail Cherkasskii (Saint Petersburg State University) who recently joined us for a 3 months research stay funded by DAAD scholarships ("Research stays for University Academics and Scientists, 2020" and "Dmitrij Mendeleev" Program).

Dr. Natalia Shkodich is an expert on combining High-Energy Ball Milling (HEBM) and Spark Plasma Sintering (SPS) to produce nanostructured and amorphous materials from immiscible metals (so-called pseudo alloys), metallic glasses, and high-entropy alloys (HEAs). She aims at producing novel nanostructured CoCrFeNiGa magnetic high entropy alloy (Mag HEA) particles and volume MagHEA materials with a large magnetization, high Curie temperature and tuneable coercivity as well as excellent mechanical properties.

Interests of Assoc. Prof. Dr. Mikhail Cherkasskii are focused on the understanding of magnetization nutation in ferromagnets and its coupling to precession and ferromagnetic resonance. He is working on the development of an analytical approach to describe inertial spin dynamics, nutation resonance and collective excitations in ferromagnets.

2020-07-24: New publication in AIP Advances - Editor's Pick!
Reversal of uniaxial magnetic anisotropy in Fe/GaAs (110) films driven by surface relaxation: An in situ ferromagnetic resonance study by Babli Bhagat et al.

Performing in situ studies of ferromagnetic resonance in thin metallic films in ultrahigh vacuum, we found a dramatic change of in-plane magnetic anisotropy in 4 nm Fe film grown on GaAs(110) substrate occurring after deposition. Initially grown, Fe/GaAs(110) film exhibits unusual uniaxial in-plane anisotropy which reverses its sign within 40 hours while the film is kept in vacuum at room temperature. The effect of surface contamination has been excluded using surface-sensitive techniques AES and LEED, which let us to conclude on metastability and ongoing surface relaxation of Fe film. This finding opens up a further study of such island-like grown metastable thin films where magneto-morphological transitions can be altered by temperature and other external stimuli.
2020-03-10: Non-standing spin-waves in confined micrometer-sized ferromagnetic structures under uniform excitation
Editors Pick (!) Non-standing spin-waves in confined micrometer-sized ferromagnetic structures under uniform excitation Appl. Phys. Lett. 116, 072401 (2020); https://doi.org/10.1063/1.5139881 Santa Pile et al. A long effort within an international collaboration (U. Linz, Duisburg-Essen, Stanford) including partners from the CRC/TRR 270 broke new ground in element-specific magnetic imaging with picosecond temporal and few nanometer spatial resolution. A non-standing characteristic of directly imaged spin-waves in confined micrometer-sized ultrathin Permalloy (Ni80Fe20) structures is reported along with evidence of the possibility to alter the observed state by modifications to the sample geometry.
