Field(s) of expertise during doctoral studies:
- Near-field optical microscopy (SNOM) imaging of magnetic materials and photonic structures
- Brillouin light scattering (BLS) on magnetic materials
Curriculum Vitae
- Doctoral studies in the Optics Group of Prof. Dr. Georg Woltersdorf at MLU from 2019 till now
- Master of Science in Physics at MLU in 2019
Challenges, rewards and contribution
Q: What was your most important contribution to the publication?
A: I conducted a large part of the measurements and simulations presented in this work. In addition I was involved in writing the manuscript and prepared the figures.
Q: What was challenging and what was a rewarding moment during your work presented in the publication?
A: The most challenging aspect was to make sense of all the data collected in the first place, to exclude possible artifacts and develop a model of the fundamental process we observed. When the different measurements and simulations fit together so perfectly and confirmed each other, we realized that it really was something new we had discovered which was quite rewarding.
Significance of publication
A new discovery could make certain components in computers and smartphones obsolete. The team has succeeded in directly converting frequencies to higher ranges in a common magnetic material without the need for additional components. Frequency multiplication is a fundamental process in modern electronics.
