      abstract     = {We address the importance of the modern theory of orbital
                      magnetization for spintronics. Based on an all-electron
                      first-principles approach, we demonstrate that the
                      predictive power of the routinely employed
                      “atom-centered” approximation is limited to materials
                      like elemental bulk ferromagnets, while the application of
                      the modern theory of orbital magnetization is crucial in
                      chemically or structurally inhomogeneous systems such as
                      magnetic thin films, and materials exhibiting nontrivial
                      topology in reciprocal and real space, e.g., Chern
                      insulators or noncollinear systems. We find that the modern
                      theory is particularly crucial for describing magnetism in a
                      class of materials that we suggest here—topological
                      orbital ferromagnets.},
