Title of the Research: Application of computational methods for the study of the correlations between the structure and the magnetic and electronic properties of hybrid systems containing organic molecular magnets and/or based on coordination compounds

Description: The main objective of the project is to achieve a deeper understanding of the microscopic mechanisms underlying the magnetoelectric effect and chiral-induced spin selectivity (CISS). In this regard, a series of interesting molecular and spinterface systems will be studied. The use of a periodic calculation approach is mandatory when working with crystals and thin films. This choice is required to consider all the possibilities from the necessity that can define the structure of molecular interest (packaging effects, polarization effects of first neighbors, etc.). Non-relativistic and scalar-relativistic methods based on the functional theory of periodic density (p-DFT) can guarantee accuracy on geometric parameters and detect any magneto-electric and CISS effects. They can be used as approaches on mixed Gaussian and plane waves or pure plane waves. The anisotropy of the magnets can therefore be calculated on the geometries obtained in homogeneous electric fields or selectively applied to particular directions. Pure scalar-relativistic methods will also be used within post-HF approaches on single molecules extracted from p-DFT geometries by applying a more accurate calculation of the static and dynamic required for accurate computations of magnetic properties. For CISS systems, the most favorable adsorption site will be found for the different chiral molecules by thermodynamic criteria. Static or dynamic sampling will be used. The density of states and the magnetic/spectroscopic properties of hybrid systems will be studied. Finally, DFT/post-HF approaches on simple cluster models will also be considered for a more accurate electronic/magnetic characterization of the chiral molecules once adsorbed.
