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…
Structural view of hexagonal non-perovskite AMnO3
Bas B. van Aken, Auke Meetsma, Thomas T. M. Palstra
We refined the crystal structure of AMnO3, with A = Y, Er, Yb and Lu by single crystal x-ray diffraction. Our results show some distinct differences with previous reports on LuMnO3…
La-site shift as probe for Jahn-Teller effect
Bas B. van Aken, Auke Meetsma, Thomas T. M. Palstra
We observe two consecutive transitions in La1-xCaxMnO3, x=0.19: ferromagnetic ordering at Tc = 177 K and Jahn-Teller orbital ordering at T_JT = 150 K. The presence of a ferromagnet…
