Scientific project

Feb 2021 – present: Valence delocalisation within Mixed-valence Molecular Clusters
PhD project
· Studying spin dynamics of mixed valence molecules using neutron spectroscopy
· Investigating the influence of applied electric fields to said clusters
· Modelling of the magnetic properties and neutron spectra with numerical methods
Nov 2019 – Dec 2021: Studies of magnetic properties in Layered Double Hydroxides
Master’s project
· Studied aluminium hydroxide-based layered double hydroxides (LDHs) with Cu2+, Ni2+ and Co2+
· Performed bulk magnetic measurements to determine the magnetic properties
· Used inelastic neutron scattering to measure the magnetic spectrum of Ni-LDH
· Used neutron powder diffraction to confirm absence of magnetic ordering in Ni-LDH down to 2 K
Jan 2017 – June 2017: Simulations of classical spin dynamics
Bachelor’s project
· Developed a program capable of simulating classical spin dynamics of up to 20 spins governed by the
exchange interaction in an external magnetic field
· Implemented the Langevin equation to account for thermally induced spin fluctuations
· Implemented a FFT-algorithm to calculate the dynamical structure factor as a function of q and energy
from the spin dynamics, which allowed for comparison to real neutron spectroscopy data.
