because of its spin order influenced ferroelectricity below ~40 ± 5 K with
an extremely large magnetoelectric coupling. In this multiferroic family,
the origin of the large magnetoelectric coupling has been thoroughly
studied especially for the members having small R<SUP>3+</SUP> ions.
However, the real microscopic origin of the ferroelectricity is still a
matter of great debate. In addition, understanding about the influence of
the R<SUP>3+</SUP> ions on the magnetic and electric orders is not clear
and further investigations are required to settle this issue. In this
