Dr. Katarzyna Siewierska completed her PhD in Physics in 2021 at University of Dublin, Trinity College. Her thesis title was `Development and Characterisation Zero-moment Half-metal'. The research involved fabrication and characterisation of Mn2RuxGa thin films using a variety of techniques including magneto-transport, magnetometry, magneto-optical Kerr effect microscopy and x-ray magnetic circular dichroism. Her main research interests are novel spintronic materials and synchrotron techniques.
