It has been reported that different ordered structures can appear at the same grain boundaries. Thermodynamically, they can be regarded as interface phases (“complexions”). The authors use atomistic simulations to show that several fcc transition and post-transition metals exhibit the same two grain boundary phases in [111] tilt grain boundaries. This remains true even when using unphysical pair potentials, highlighting that the occurrence of different grain boundary phases is not an exceptional special case, but common across different materials.

The energy barrier for polarization reversal is a key property that impacts the performance of ferroelectric materials. Here, the authors combine symmetry analysis and first-principles calculations to understand the origin of low-energy polarization switching in the Aurivillius-phase ferroelectrics SrBiTaO and SrBiNbO. They show that polarization reverses via a low-energy two-step process facilitated by nonpolar structural order parameter rotations. Analysis of the ferroelectric domain structure shows that the formation of domain wall vortices is energetically favorable.
