Picosecond vortex dynamics in magnetic nanostructures: the interaction between vortices and spinwaves Ghent University
Being the simplest non-trivial configurations of magnetic nanostructures, vortices are not only interesting study objects, but offer new perspectives for magnetic data storage. An optimally pulsed synchrotron X-ray source will be used to investigate the ultra fast dynamics of the vortex core in an X-ray microscope. Additionally, the interaction of spin waves with the core dynamics will be investigated.
Picosecond vortex dynamics in magnetic nanostructures: the interaction of vortices with spinwaves. Ghent University
In this project, we will address the interaction of spin waves with vortices and domain walls. These have their own dynamics, and understanding how spin waves can interact can lead to new functional magnetic devices. Magnetic resonance spectroscopy, time-resolved X-ray microscopy and advanced simulation tools will be deployed to study these interactions in nanometer sized wires and platelets.
Scanning Hall probe microscopy of vortex matter in artificial type-1.5 and low-k superconductors. KU Leuven
The proposed project aims at deepening our understanding of the intricate vortex-vortex interactions that determine the vortex patterns and related superconducting properties in type- 1.5 and low-k superconductors. It is well known that superconductors can be categorized into type-I and type-II by the Ginzburg-Landau parameter k. While in type-I superconductors, vortices experience a short-range attractive interaction leading to the formation ...

Local probing of the dynamics of the superconducting condensate. KU Leuven
A magnetic field penetrates into a type-II superconductor in the form of quantized units of magnetic flux, called vortices. Besides a localized magnetic field they are characterized by a depletion of the superconducting condensate. Bearing in mind the concept of “seeing is believing”, scanning probe microscopy techniques played a crucial role in probing the static vortex distribution with nanometer resolution. The motion of these fascinating ...
Exploiting the internal dynamics of inhomogeneous magnetization states for technological and biomedical applications. Ghent University
The interplay of different interactions gives rise to complex magnetization structures on the nanoscale, like vortices and skyrmions. These structures can display internal inhomogenous dynamics, which is for instance the case in the technologically relevant regime where the driving forces are relatively weak compared to thermal excitations. In this project, we will exploit these inhomogeneous dynamics with the aim to improve a ...

Computational fluid dynamics based design of downers with the implementation of detailed chemistry Ghent University
Fluid catalytic cracking (FCC) is one of the major conversion technologies in the oil refinery industry and produces the majority of the world’s gasoline. FCC Is conventionally performed in a circulating rising fluidized bed reactor, however, the usage of down-flow reactors offers several advantages such as less species back-mixing and more narrow residence time distributions. Experimental studies have shown that in both riser and downer ...
