Electrically tuneable interactions between molecular nanomagnets on graphene

In this project we will investigate the electrical tuning of magnetic couplings between molecular nanomagnets (MNM) on graphene. The long-range ordered arrays of MNMs will be prepared on graphene surfaces employing self-assembly mechanisms. We will exploit the possibility of tuning the graphene Fermi level by means of a gate voltage and explore the possibility of modulation of the magnetic coupling between MNMs. In particular, we will employ the electron spin resonance to assess the low-energy electronic structure of the MNMs, their magnetic coupling and investigate their coherent properties. Additionally, we will measure the orientation and magnitude of the magnetic moments via torque magnetometry. These measurements will be explained with help of ab-initio DFT calculations. The project is of great fundamental interest, as many conflicting predictions exits regarding strength and distance dependence of such indirect magnetic couplings. Furthermore, the outcomes of this project may have important impact in the fields of molecular spintronics and quantum information processing.
