Disorder induced hexagonal-orthorhombic transition in (Y,Gd)MnO3

Jan-Willem Bos, Bas B. van Aken, Thomas T. M. Palstra

We show that the transition in AMnO3 from the orthorhombic perovskite phase to the hexagonal phase is promoted by inducing disorder on the A-site. The gap between the orthorhombic…
