Abstract

The effects of magnetic fields and external pressure on the multiferroic properties and the ferroelectricity in DyMn₂ O₅ are studied. With fields applied along the hard magnetic axis the new high-field phase previously detected is shown to be paraelectric. Application of pressure enhances the ferroelectric polarization at low temperatures by stabilizing the commensurate Mn-spin order. The pressure-temperature phase diagram is resolved.
