The structure can be described by modulations associated with the lattice vibrational mode Σ3(TO) with q (0.15,0.15,0)and the Rxy 25 mode, although the latter modulation is relatively distorted. The size of the orthorhombic unit cell is p2 × 10p2 × 2 times as large as that of the high-temperature cubic cell. The space group is Pbam-D9 2h (No. 55), and is the same as that of the room-temperature antiferroelectric (A1) phase of PbHfO3. © 2018 Physical Society of Japan.
