Abstract
RMn2 compounds (R = Gd, Tb, Dy, Ho and Y) with Mn atoms substituted to 0.5% with Fe-57 were studied by means of Mossbauer spectroscopy. The hyperfine fields B(hf) Vs lattice parameter are rather similar oscilla ting around 6 T. For (Dy(FeMn)2)-Fe-57underbar the chemically equivale nt Mn sites in the unite cell are magnetically differentiated ensuing two hyperfine fields B(hf)I = 8 T and B(hf)II = 3.7 T. The electronic contribution to the electric field gradient V(zz) is negative.
