已预测常压阳离子无序InVO 3方铁锰矿在高压和高温下形成GdFeO 3型钙钛矿相。与预期相反，发现InVO 3以极性LiNbO 3-型结构结晶，计算的自发极化高达74 μC cm−2。 V3+磁矩的反铁磁耦合和低于约10 K与极性结构耦合的合作磁性基态表明了新型LiNbO 3型高压InVO 3结构的有趣基态。 
The ambient pressure cation disordered InVO3bixbyite has been predicted to form a GdFeO3‐type perovskite phase under high pressure and high temperature. Contrary to the expectation, InVO3was 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 InVO3structure.
