Description

Microscopic magnetism and dielectric properties in the multiferroic rare-earth manganites of RMn2O5 studied by neutron diffraction and dielectric measurements are reviewed.It has been revealed that RMn2O5 shows successive dielectric and magnetic phase transitions, which concomitantly take place and are induced by temperature, magnetic field, and hydrostatic pressure.This coexistence and mutual coupling between dielectric and magnetic order, as well as the induced 4f magnetic moment on rare-earth ions, are ingredients essential for realizing a rich variety of colossal magnetoelectric effect.
