Giant magnetoelectric effect in multiferroic HoMnO3 with a high ferroelectric transition temperature

Year: 2009

Type: article

Abstract: We present an example of giant magnetoelectric effect in a conventional multiferroic ${\text{HoMnO}}_{3}$, where polarization is very large $(\ensuremath{\sim}56\text{ }\text{mC}/{\text{m}}^{2})$ and the ferroelectric transition temperature is higher than the magnetic ordering temperature by an order. We attribute the characteristic of the giant magnetoelectric effect to the ferroelectricity induced entirely by the off-center displacement of rare-earth ions with large magnetic moments. This finding suggests an avenue to design multiferroics with large polarization and higher ferroelectric transition temperature as well as large magnetoelectric effects.
