Hexagonal Manganites—(RMnO3): Class (I) Multiferroics with Strong Coupling of Magnetism and Ferroelectricity
Figure 14
Derivative of the inverse magnetic susceptibility, , of HoMnO3 at different high magnetic fields. In (a) different curves are vertically offset for better clarity. In (b) all data are shown at the same scale. The dashed line indicates the T-dependence of the derivative in the intermediate phase.
