The development of topological quantum chemistry has proven to be a game changing tool for predicting topological phases in realistic materials, both non-magnetic and magnetic. Building on the work of previous studies, in this work we expand the family of magnetic insulators and semimetals with non-trivial topological properties. We analyzed 408 magnetic structures from the Bilbao Crystallographic Server magnetic database, whose crystal and magnetic structures have been experimentally reported. To take into account the localized nature of magnetic elements, we perform electronic structure calculations and topological diagnosis as a function of the Hubabrd U parameter. This results in a topological phase iagram for each material as a function of the Hubbard interaction potential. We provide full details of the materials, which can be readily grown to explore their new topological phenomena.
