In situ synchrotron X‐ray diffuse scattering and inelastic neutron scattering measurements from a prototype ABO 3 ferroelectric single‐crystal are used to elucidate how electric fields along a nonpolar direction can enhance its piezoelectric properties. The central mechanism is found to be a nanoscale ordering of B atom displacements, which induces increased lattice instability and therefore a greater susceptibility to electric‐field‐induced mechanical deformation.
