Field-cycling history dictates severe spatial asymmetry in the pyroelectric response of BaZr0.2Ti0.8O3, proving that non-ergodic relaxor domains and ordered ferroelectric phases directly coexist at near-ambient temperatures.

Systematic phase evolution in Sm-doped BiFeO3 reveals a striking transition from extended ferroelectric domains to a connected nonpolar state, driven by composition changes.
