The main purpose of this Thesis is to perform a theoretical analysis of the
magnetism and electronic correlation on different nanochain systems. Though
simple in their structure, they show intriguing magnetic properties due to
their low dimensionality.
We focus on two different types of chains: transition metal oxide chains with
stoichiometry XO where X=Ni, Co, Fe and Mn grown on Ir(100) and the metal-
organic polymeric CoQDI and CrQDI chains. In the former chain, we study the
electronic correlation variation between the planar unsupported and the
supported system. Depending on the interaction between substrate and chain,
the magnetic atom electron occupancy can be entirely modified and interaction
between the electrons affected, thus, modifying the magnetic properties of the
system. In the metal-organic chains, we analyze the consequences when the
theoretical analysis is capable to converge to excited states apart from the
minimum energetic ground state. We will study the change in the magnetic
properties when the different states are set in the magnetic atoms.
