    • The nonpolar high-temperature space group of the hexagonal LnMnO 3 series is P63/mmc. All ions are constrained to planes perpendicular to the unique hexagonal axis c. With decreasing temperature a two-step transition to the non-centrosymmetric ferroelectric phase occurs: P63/mmc→P6 3cm at the temperature Tnpt of the nonpolar transition and, without change of symmetry, P63cm→ P63cm at TFE, where T npt ≈ 1430 K and TFE ≈ 1050 K determined for Ln, Tm. The first step is a paraelectric to triangular-antiferroelectric phase transition where the pseudo threefold main axis O-Mn-O of the MnO5 bipyramid tilts and the Ln layer corrugates. The subsequent triangular- antiferroelectric to ferroelectric transition is generated by a displacement of the O2

    • The mechanism that interlocks the ferroelectric and antiferromagnetic domain walls can be explained as follows:[10c] 1) The distortion at the ferroelectric domain wall as a result of to the reversal of the electric dipoles produces an elastic strain; 2 the gradual rotations of the magnetic moments across an antiferromagnetic wall result in a non-zero local magnetic moment. So, the electric and magnetic perturbations can interact through the piezomagnetic effect, Piezomagnetism describes a change in strain as a linear function of an applied magnetic field, or a change in magnetization as a linear function of applied stress
