Theoretical and computational studies of magnetic anisotropy and exchange coupling in molecular systems
2018
The field of molecular magnetism studies the magnetic properties of molecular systems as opposed to conventional metal-based magnets. The high chemical modifiability of the constituting molecules makes such materials highly versatile, and the small size of the building blocks leads to the rise of various quantum mechanical phenomena, such as tunneling and entanglement. These phenomena can then be further utilized in the construction of nanoscale quantum devices. This dissertation describes computational and theoretical studies in the field of molecular magnetism using state-of-the-art quantum chemical methods based on ab initio multireference approaches and broken symmetry density functional t…
Theoretical study of systems with interest in molecular magnetism and electronics
2013
The project described in this thesis is motivated by a particular interest in Molecular Magnetism from a theoretical point of view. Molecular Magnetism, is still a thriving research field where some problems remain unexplored: A large amount of molecular systems are still theoretically unmanageable due to their huge computational requirements, while the standard software package cannot profit from the power of multiprocessor supercomputers. The scientific community would require a computational code to calculate the magnetic properties of mixed-valence clusters. A new magnetic POM, which needs only one magnetic ion to behave as SMMs, has appeared. A rationalization of its behaviour and an e…
