Synergistic polar states by selective atomic gradients [Science (2026)] Materials that combine distinct properties within a single phase are of fundamental and technological interest. Here, A-site selective atomic gradients induce strong polar states in otherwise centrosymmetric perovskite oxides ABO3, leading to bulk polar metallicity with tunable nonreciprocal transport, high-κ/low-loss dielectricity with an equivalent oxide thickness below 0.1 nm, and giant pyroelectricity. more
