In this work, computational study of the magnetic anisotropy in series of transition metal complexes, when changing the metal ion, or the ligands, in a controlled way will be presented. In order to achieve this goal, ligand field DFT method (LF-DFT) is applied for the calculations of the zero-field splitting (ZFS) parameters and analysis of magnetic anisotropy. With this methodology, we accurately predict magnitude and sign of the ZFS parameters, orientation of the principal magnetic axes, and we can pin-point the excitations that control magnetic anisotropy. In this way, we rationalize the connection between the electronic structure, excited states and magnetic properties of transition-metal complexes. The present strategy will be illustrated by discussion of the magnetic anisotropy in trigonal-bipyramidal complex of Ni(II), scorpionate complexes, and octahedral complexes of Mn(IV).
