Description

In order to clarify the microstructure related to the ferroelectric properties in multi-ferroic YMnO3, we carefully examined the ferroelectric-domain configuration by transmission electron microscopy (TEM). It was found that ferroelectric domains in YMnO3 consist of six anti-phase domains at room temperature. On warming from room temperature, the ferroelectric-domain configuration changes into one consisting of three anti-phase domains around 738 K. In addition, the ferroelectric domains in YMnO3 change drastically into microdomains with a size of 10 ∼ 20 nm by substitution of Ti ions for some of the Mn ones.
