Exploring magnetism in Co-, Ni- and Cr-coordinated metal-organic frameworks on Au(111)

Metal-organic frameworks (MOFs) represent a versatile class of materials with tunable properties, offering promising avenues for applications in various fields. In this proposal, we aim to investigate the magnetic order of 2D-MOFs by varying the magnetic metal centers (Co, Ni and Cr), while preserving the organic ligand framework. We present preliminary experimental results indicating distinctive magnetic behaviors upon metal coordination by scanning tunneling microscopy and spectroscopy (STM/STS) and theoretical calculations. We anticipate that characterization through X-ray magnetic circular dichroism (XMCD) provides detailed insights into metal-centered magnetism in 2D MOFs, offering a comprehensive understanding of their magnetic properties and paving the way for tailored applications.
