Abstract

The ambient pressure cation disordered InVO₃ bixbyite has been predicted to form a GdFeO₃ -type perovskite phase under high pressure and high temperature. Contrary to the expectation, InVO₃ was found to crystallize in the polar LiNbO₃ -type structure with a calculated spontaneous polarization as large as 74 μC cm^-2 . Antiferromagnetic coupling of V³⁺ magnetic moments and a cooperative magnetic ground state below about 10 K coupled with a polar structure suggest an intriguing ground state of the novel LiNbO₃ -type high-pressure InVO₃ structure.

Keywords: High-Pressure Synthesis; LiNbO3-Type Structure; Multiple Orders; Phase Transition; Spontaneous Polarization.
