Abstract
- Motivated by the recently discovered superconductivity in Sr-doped nickelate oxides NdNiO<subscript>2</subscript> reduced from NdNiO<subscript>3</subscript> in experiments, we predict a Mott multiferroic BiNiO<subscript>2</subscript> that may be obtained from BiNiO<subscript>3</subscript>. There is a ferroelectric structural transition for BiNiO<subscript>2</subscript> from the nonpolar phase to the polar phase with the P4mm space group, which is driven by the lone pair on Bi. The lowest energy ground-state for polar BiNiO<subscript>2</subscript> is a Hubbard Mott insulator with the G-type antiferromagnetic spin configurations. The replacement of Nd by Bi serves as a connecting link between a parent compound of high-temperature superconductor and a Mott multiferroic. [ABSTRACT FROM AUTHOR]
