I am a Ph.D. student at the Niels Bohr Institute in the X-ray and Neutron Scattering group. In this group we study the role of magnetism in materials. In particular, we are interested in the connection between the magnetism and the functionality of materials. To do this we use the neutron scattering technique, which is a non-destructive, penetrating technique that allow us to obtain unique information on the structure and dynamics of materials. It allows us to directly and quantitatively measure spin correlations in both space and time, which provides detailed information on the magnetic ground state and the magnetic excitations of a system. Sufficiently intense neutron beams cannot be produced in the lab. Instead, we perform our experiments at dedicated large-scale facilities such as reactors and accelerator-based sources.

In my Ph.D. project “Investigation of frustrated magnetic materials with the technique inelastic neutron scattering”, I study frustrated magnetism, meaning that not all exchange interactions can be fulfilled at the same time resulting in the spin frustration. In frustrated magnets the energy landscape is very shallow and complicated, which in turn presents an excellent ground to discover new states and new properties of matter. Often, we think of a system being either magnetically ordered leading to spin waves or magnetically disordered showing broad diffuse scattering, but this does not seem to be true for all frustrated systems, we have observed that the border between the two phases is not as sharp. In my project, I aim to understand the cause of this large overlap of order and disorder by investigating multiple frustrated systems. We have already observed this behaviour in three frustrated materials, and I am currently working on mapping the origin of how and why we see this large overlap only for frustrated systems.
