      abstract     = {Magnetic rare-earth ortheferrites of the RFeO3 type (R =
                      rare earth element, model systems for studies and
                      theoretical considerations on magnetic structures in sixties
                      of the last century [[Whi69, Mar70, Ber68], have regained
                      significant interest in the last decade. Their complex
                      multiferroic and magnetocaloric features make them potential
                      candidates for modern applications, e.g. in the area of
                      spintronics [Tok12, Lee11]. We recently completed an
                      extended project, Mechanisms for multiferroicity in
                      rare-earth orthoferrites: Role of the Dzyaloshinskii-Moriya
                      interaction, funded by the DFG (SA-3688/1-1). In this
                      project we used various experimental methods to gain an
                      overview of the exchange parameters of different magnetic
                      exchange interactions, the Heisenberg-exchange, the
                      Dzyaloshinskii-Morya interaction, the single-ion anisotropy
                      and external magnetic fields for different RFeO3 compounds.
                      A close quantitative examination and comparisons with
                      results from other groups reveal that the different
                      parameters differ significantly between the different
                      systems [Ovs22a, Ovs22c], . This causes a fragile balance
                      between them and results in very different magnetic phase
                      diagrams e.g. for HoFeO3, TbFeO3 and YbFeO3. [Ovs22a, Art12,
                      Ovs22c], In addition, we also looked at TmFeO3 and DyFeO3 as
                      part of our project and wWe were also able to achieve
                      initial information for them. In our presentation, we
                      provide an overview of the results of the orthoferrites we
                      examined.[Art12] S. Artyukhin et al.; Nature Mater. 11
