PhD: Correlating magnetotransport with magnetic microstates in nanoscale 3D magnetic metamaterials

This project aims to establish, for the first time, a direct correlation between magnetotransport properties and the underlying magnetic microstate in 3D artificial spin-ice (ASI) lattices. Using state-of-the-art two-photon lithography followed by conformal metal deposition, we will fabricate diamond-bond 3D ASI structures with controlled bond angles and lattice spacings.

The magnetic microstate will be imaged across different field and thermal histories using MFM, magneto-optical Kerr effect (MOKE) imaging, and synchrotron-based X-ray magnetic circular dichroism (XMCD). In parallel, electrical measurements including anisotropic magnetoresistance (AMR) will probe the collective response of the lattice. By correlating these datasets, we will uncover how specific vertex configurations and microstate populations control electronic transport.
