Hexagonal Manganites—(RMnO3): Class (I) Multiferroics with Strong Coupling of Magnetism and Ferroelectricity
Figure 39
Heat capacity of YbMnO3 at zero magnetic field. The -shaped anomaly at indicates the second order transition. At about 4 K, the sharp peak (enlarged in the inset) results from the ferrimagnetic order of the moments on 2a and 4b sites.
