Deskripsi
The competition between the polar and nonpolar phase in the prototypical hybrid improper ferroelectric crystal Ca3Mn2O7 leads to exotic properties. Here, the authors directly imaged the crystal at atomic resolution to understand its nanostructure and discovered the double bilayer polar nanoregion.
