- Abstract
- Neutron scattering studies were performed on a single crystal of multiferroic TbMn2O5. The neutron intensities were observed at magnetic modulation peaks in the ferroelectric phase. The temperature dependences of the magnetic peak intensities in the low-temperature incommensurate phase imply that there exist multiple magnetic orders with different temperature dependences. The results are consistent with discommensuration as an explanation for the re-entrant low-temperature incommensurate magnetic phase transition at 24 K.
