Transparent Tissues and Porous Thin Films: A Brillouin Light Scattering Study
… tissues in the eye that control the focusing of light, while strains within nano-scale films and coatings in the next generation of microelectronic devices could have profound effects on their functionality. Measurement of the elastic properties of such microscale structures has however proven …

A Play of Light and Spins: Excitation and Detection of Non-linear Magnetization Dynamics using Light
… pulsed laser, and study the same with a Brillouin Light Scattering (BLS) microscope. Further, we explore the synchronization characteristics of spin-Hall nano-oscillator (SHNO) arrays and their applicability to neuromorphics and Ising machines, using electrical measurement as well as …

Magnetische Anisotropie und Spintransport in magnetoelektronischen Schichtsystemen und Nanostrukturen
… beam epitaxy (MBE) and examined ex situ by Brillouin light scattering (BLS). The frequency of the Damon Eshbach spin wave mode was measured for each thickness as a function of the angle between the external magnetic saturation field and a selected in plane direction of the sample. By fitting …

Nanostructured magnetic materials for integrated magnonic devices
… coupling. Additionally, the field-dependent Brillouin Light Scattering (BLS) spectra unveil distinct spin wave modes, with ES films showing well-resolved bulk and Damon-Eshbach surface spin wave modes, while non-ES films exhibit mode doublets below a certain applied field threshold. These …

Unique templating of and applications enabled through mesoporous colloids
… and used as a template for silicon deposition. Brillouin Light Scattering (BLS) experiments conducted on a silicon templated silica colloidal crystal show unusual behavior in the BLS spectrum where the Stokes and anti-Stokes phonon intensities were asymmetrical. The dispersion relationship …
