Magnetic hardening of metal-organic 2D materials via integration of heavy d-block or f- elements

The integration of heavy d-block elements offers a promising route for enhancing the magnetic hardness of low-dimensional metal-organic materials. Our previous experiments demonstrated that TCNE based MO layers coordinated with Ni, Fe or a mix of the two elements exhibit stable ferromagnetic ordering. In the latter case, the interplay of the metal ions significantly improved the magnetic stability at the Fe center. Motivated by these findings, we propose to further improve the magnetic properties of NiTCNE by embedding Pt, Ir and Er atoms. These high-Z elements, despite being non-magnetic in their pure form (in case of Pt, Ir), contribute significantly to magnetocrystalline anisotropy via strong spin-orbit coupling. By using synchrotron-based X-ray spectroscopy and magnetic characterization techniques, we aim to quantify the effects of heavy element incorporation on the magnetic properties of the system. Our research aims to advance the development of magnetically robust 2D metal-organic frameworks, which hold potential for spintronic applications and high-density data storage.
