This research provides the electronic and magnetic characterization of a metal-organic networks formed using Iron-Tetrakis-(4-Cyanophenyl) Porphyrin (Fe-TCPP) and Dysprosium (Dy). By carefully depositing specific amounts of Fe-TCPP and Dy on Au(111), coordinated bonding between Dy and cyano-groups led to organized structures, forming extensive 2D islands and showcasing significant long-range ferromagnetic order. We used scanning tunneling microscopy/spectroscopy, x-ray magnetic circular dichroism and density functional theory to explore the structural and magnetic attributes of a metal-organic coordination network based on lanthanides. This method of fabrication lays the groundwork for creating magnetic 2D architectures on surfaces capable of storing and manipulating quantum information. This advancement propels the boundaries of quantum computing and information processing, potentially enabling the development of multiqubit systems.
