Single-molecule magnets have recently gained significant interest for their ability to retain magnetic information at the molecular level, surpassing the superparamagnetic limit of conventional magnetic storage technologies and offering potential applications in ultra-compact and high-density data storage devices. A crucial challenge hindering their application in technology is the integration with thin-film devices. To master this challenge, we explore the spin-orbit coupling in hybrid single-molecule magnet/non-magnetic metal thin film heterostructures to understand the impact of hybridization. For this, we inject a pure spin current at ferromagnetic resonance into the hybrid interface, allowing us to measure the spin-to-charge conversion efficiency. In this work, we utilize single-molecule magnets based on the metallacrown system, chosen for their unique combination of reliability and versatility. Quantifying the adsorption for molecular systems with different constitutions and planarity allows us to conclude the impact of molecular structure on the effective spin-orbit coupling and magnetic coupling at the hybrid interface, paving the path toward novel spintronic devices.

Keywords: Ferromagnetic resonance; Single-molecule magnets; Spin-orbit coupling; Inverse spin Hall effect
