Abstract
The magnetostructural phase diagram of multiferroic TbMn2O 5 was investigated as a function of temperature and magnetic field by neutron diffraction. It was observed that dielectric and magnetic anomalies were associated with steps in the magnetic propagation vector, and in the structural parameters. The geometrically frustrated magnetic structure were found to be stabilized by "canted antiferroelectric" displacements of the Mn3+ ions. It was found that the Tb moments order ferromagnetically at low temperatures in an applied field, while the Mn magnetic structure is largely unchanged.
