Artificial Shakti ice magnets: ground state degeneracy, Coulomb phase and monopole excitations
Zálešák, Marek ; Hrabec, Aleš (oponent) ; Rougemaille, Nicolas (vedoucí práce)
Artificial spin systems have emerged as a promising platform for studying in real space and harnessing exotic states of matter. This diploma thesis investigates the unique properties of a specific artificial spin system known as the shakti ice magnet. The shakti ice magnet is a two-dimensional arrangement of interacting nano-magnets, exhibiting intriguing magnetic behaviour. This research aimed at characterising its behaviour and its ability to be mapped onto the seminal square ice in which interesting Coulomb physics is expected. A combination of experimental measurements and numerical simulations was employed to achieve these objectives. Experiments were based on MFM measurements to determine the magnetic configuration of samples containing lithographically prepared shakti lattices.
