Abstract
The crystal structure of hexagonal yttrium trioxomanganate has been determi ned at room temperature and at 180 K. It is isomorphous with LuMnO3. The Mn displacement vector has a frustrated component in the ab plane and a ferro electric part along the c axis. The net ferroelectricity is zero due to inv ersion twinning, with 1:1 twin fractions.
