On the magnetically driven ferroelectric phase in GdMnO3

At room temperature, GdMnO3 is a paraelectric and paramagnetic with a distorted perovskite structure of orthorhombic symmetry (space group Pnma). On cooling, it undergoes a phase transition sequence to a magnetic incommensurate phase ( k = δ(T ) a∗; Tc1 = 42 K) and a A-type antiferromagnetic phase (...
