Аннотация: Neutron diffraction and Mossbauer spectroscopy have been used to examine the connections between long-and short-range magnetic order in the rare-earth iron ferroborate YFe3(BO3)(4). We establish the presence of short-range magnetic order in the pseudo-one-dimensional Fe-spin chains of the FeO6 octahedra while the ferroborates are in their (long-range) paramagnetic phase. The short-range order exists at temperatures several times the Neel temperature. In addition, we observe thermal hysteresis of the short-range ordered Fe spins. The observed Fe-spin dynamics are suggestive of the presence of solitons within the domains that form in the Fe-spin chains.
