The goal of this project is to perform further exploration of the thermodynamics in two-dimensional artificial frustrated systems. Taking advantage of state-of-the-art nanofabrication tools, we will design and fabricate novel geometrically frustrated magnetic metamaterials. Then, using synchrotron-based sample characterizations methods such as photoemission electron microscopy (PEEM), we aim to investigate the thermodynamics of these systems with the main goal to explore a variety of emergent phenomena ranging from emergent magnetic monopoles, magnetic charge screening effect, to novel types of emergent frustration.
