Ground state and constrained domain walls in Gd/Fe multilayers
Bas B. Van Aken, Jose L. Prieto, Neil D. Mathur
The magnetic ground state of antiferromagnetically coupled Gd/Fe multilayers and the evolution of in-plane domain walls is modelled with micromagnetics. The twisted state is charac…
Influence of antiferromagnetic ordering on ferroelectric ordering in LuMnO3
Bas B. Van Aken, Thomas T. M. Palstra
We have studied the influence of antiferromagnetic ordering on the local dielectric moments of the MnO_5 and LuO_7 polyhedra by measuring neutron powder diffraction patterns of LuM…
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…
Twin model for orthorhombic perovskites
Bas B. Van Aken, Auke Meetsma, Thomas T. M. Palstra
We present a detailed single crystal x-ray diffraction study of twinned orthorhombic perovskites. The diffraction pattern can be indexed on a xx lattice, but does…
