Many thanks to Prof. Ulrike Wallrabe for hosting Muireann de h-Óra during her secondment at Voxalytic, University of Freiburg. Also thanks to Hidelberto Macedo-Zamudio for helping Muireann model her 3D nanostructures using COMSOL. These secondments are part of the BeMAGIC project that focuses on magnetoelectric materials. We look forward to continuing this collaboration with the group in Freiburg.
