Structural and Magnetic Properties of the Double Perovskite LaCaMnNbO6. —
structural and magnetic properties of the double perovskite of title are investigated
06- 017 The
using neutron powder diffraction and SQUID magnetometry. LaCaMnNbO6 has a
monoclinic P21/n superstructure with an almost fully ordered rocksalt arrangement of
Mn and Nb over the perovskite B-sites. Magnetization measurements reveal a sharp
antiferromagnetic transition at TN = 9 K. The low temperature antiferromagnetic ordering is described by a magnetic propagation vector of (0 1/2 1/2). Two collinear solutions are found for the magnetic structure. — (BOS, J.-W. G.; ATTFIELD*, J. P.; Z.
