The cover picture of the present issue of physica status solidi (b) is a Fourier map calculated from the Pba 2 space group, which corresponds to the ferroelectric structure of PbK 2 LiNb 5 O 15 . It was revealed by synchrotron X‐ray powder diffraction investigations reported in the paper [1]. Positions of the various Pb, K, and O atoms in the unit cell are indicated by the labels.
