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
