2014年10月21日 · A combined structure analysis by synchrotron X-ray and neutron powder diffraction and high-angle annular dark-field scanning transmission electron microscopy imaging reveals that this compound adopts the polar R 3 c symmetry with a fully ordered arrangement of trivalent Sc and Fe ions, forming highly distorted ScO 6 and FeO 6 octahedra.

2016年11月9日 · We investigate the electronic structure and the ferroelectric properties of the recently discovered multiferroic $ {\mathrm {ScFeO}}_ {3}$ by means of ab initio calculations.

2014年10月29日 · Multiferroic materials have been the subject of intense study, but it remains a great challenge to synthesize those presenting both magnetic and ferroelectric polarizations at room temperature. In this work, we have successfully obtained LiNbO3-type ScFeO3, a metastable phase converted from the orth …

2014年10月21日 · In this work, we have successfully obtained LiNbO3-type ScFeO3, a metastable phase converted from the orthorhombic perovskite formed under 15 GPa at elevated temperatures.

2017年10月20日 · Open questions about ScFeO 3 can be addressed by confronting observations with results for G-type antiferromagnetism allowed by the lithium niobate (LiNbO 3 )-like parent R3c structure.

2016年6月3日 · The properties of newly discovered polar ScFeO3 with magnetic ordering are examined using Ab initio calculations and symmetry mode analysis. The GGA+U calculation confirms the stability of polar R3c Phase in ScFeO3 and the pressure induced phase transition to non-polar Pnma phase.
