Hexagonal Manganites—(RMnO3): Class (I) Multiferroics with Strong Coupling of Magnetism and Ferroelectricity
Figure 37
Magnetic phase diagram of TmMnO3 in -axis fields up to 120 kOe. The phase boundaries are defined by distinct anomalies of the dielectric constant , shown in Figure 36. The red lines are a guide for the eye. The closed and open symbols are refer to anomalies of and , respectively.
