A high pressure study of the novel hybrid improper ferroelectric HgMn7O12

We have recently discovered how a novel type of hybrid improper ferroelectricity can arise in the perovskite HgMn3Mn412. This ferroelectricity is driven by a highly unusual...我们近日发现，一种新型混合非本征铁电性（hybrid improper ferroelectricity）可在钙钛矿（Perovskite）HgMn3Mn412中产生。此种铁电性由一种极不寻常的……所驱动。
