      abstract     = {Magnetic exchange interactions determine the magnetic
                      groundstate, as well as magnetic excitations of materials
                      and are thus essential to the emerging and fast evolving
                      fields of spintronics and magnonics. The magnetic force
                      theorem has been used extensively for studying magnetic
                      exchange interactions. However, short-ranged interactions in
                      itinerant magnetic systems are poorly described by this
                      method and numerous strategies have been developed over the
                      years to overcome this deficiency. The present study
                      supplies a fully self-consistent method for systematic
                      investigations of exchange interactions beyond the standard
                      Heisenberg model. In order to better describe finite
                      deviations from the magnetic ground state, an extended
                      Heisenberg model, including multi-spin interactions, is
                      suggested. Using cross-validation analysis, we show that
                      this extended Heisenberg model gives a superior description
                      for non-collinear magnetic configurations. This
                      parameterisation method allows us to describe many different
                      itinerant magnetic systems and can be useful for
                      high-throughput calculations.},
