Structural modelling of octahedral tilts in perovskites is typically carried out using the symmetry constraints of the resulting space group. In most cases, this introduces more degrees of freedom than those strictly necessary to describe only the oc

Data-driven approaches in materials science demand the collection of large amounts of data on the target materials at synchrotron beamlines. To accurately gather suitable experimental data, it is essential to establish fully automated measurement sys

The complex chemical and structural heterogeneity of relaxor ferroelectrics has made the origins of the giant piezoresponse extremely difficult to understand. Here, we successfully grew Ho-doped Pb(Mg1/3Nb2/3)O3–PbTiO3 (Ho-PMNT) single crystals wit
