Abstract

Single crystals of the perovskite nickelate NdNiO<subscript>3</subscript> with dimensions of up to 50 μm on edge have been successfully grown using the flux method at a temperature of 400 °C and oxygen pressure of 200 bar. The crystals were investigated by a combination of techniques, including high-resolution synchrotron X-ray single-crystal and powder diffraction and physical property measurements such as magnetic susceptibility and resistivity. Resistivity measurements revealed a metal-insulator transition (MIT) at T<subscript>MIT</subscript>~180 K with apparent thermal hysteresis; however, no superlattice peaks or peak splitting below T<subscript>MIT</subscript>, which corresponds to a structural transition from Pbnm to P2<subscript>1</subscript>/n, was observed. The successful growth of NdNiO<subscript>3</subscript> crystals at relatively low temperatures and oxygen pressure provides an alternative approach for preparing single crystals of interesting perovskites such as RNiO<subscript>3</subscript> (R = Sm-Lu) and parent phases of superconducting square planar nickelates.
