The use of nuclear techniques, mainly Time Differential Perturbed Angular Correlation Spectroscopy (PAC), for the study of materials provides information on the interactions between the energy levels of an atomic nucleus with the electrmagnetic fields surrounding this nucleus, and this type of phenomenon is called Hyperfine Interactions (HI). The information on these interactions is contained in various hyperfine quantities, among which the most important are the Electric Field Gradient (EFG) and the Magnetic Hyperfine Field (MHF). Given the gigantic scientific capacity of electronic structure calculations based on Density Functional Theory (DFT), they are a great tool for the investigation of HIs either as a purely theoretical study or as ...
