Hexagonal Manganites—(RMnO3): Class (I) Multiferroics with Strong Coupling of Magnetism and Ferroelectricity
Figure 13
Magnetic phase diagram of HoMnO3 between and . Blue open and solid circles are phase boundaries derived from and scans, respectively. Solid stars are derived from anomalies of the -axis magnetization. The red dashed line is the phase boundary from [109]. The low-temperature ( K) section of the phase diagram will be discussed separately.
