Abstract

Ultrafast optical pump-probe spectroscopy is used to reveal the coexistence of coupled antiferromagnetic/ferroelectric and ferromagnetic orders in multiferroic TbMnO 3 films through their time domain signatures. Our observations are explained by a theoretical model describing the coupling between reservoirs with different magnetic properties. These results can guide researchers to creating unique kinds of multiferroic materials that combine coupled ferromagnetic, antiferromagnetic, and ferroelectric properties in one compound.
