Hexagonal Manganites—(RMnO3): Class (I) Multiferroics with Strong Coupling of Magnetism and Ferroelectricity
Figure 10
Thermal expansion parameters of HoMnO3. The relative length changes of the hexagonal - and -axes are shown in the main panel. The upper inset displays the thermal expansivities and the lower inset shows the change of at the first spin rotation transition.
