Molecule-like cluster magnetism and cationic order in the new hexagonal perovskite Ba(4)Sn(1.1)Mn(2.9)O(12)

The new hexagonal perovskite phase of composition Ba(4)Sn(1.1)Mn(2.9)O(12) has been synthesized by solid-state reactions at 1673 K. The crystal structure has been investigated using X-ray and neutron diffraction. The hexagonal perovskite structure has an ordered arrangement of Sn and Mn ions on the...

description The new hexagonal perovskite phase of composition Ba(4)Sn(1.1)Mn(2.9)O(12) has been synthesized by solid-state reactions at 1673 K. The crystal structure has been investigated using X-ray and neutron diffraction. The hexagonal perovskite structure has an ordered arrangement of Sn and Mn ions on the corner-sharing octahedral centers and the face-sharing octahedral centers respectively. Short Mn–Mn distances have been evidenced in the face-sharing trimer of MnO(6) octahedra. The magnetic susceptibility shows magnetic cluster behavior, with cluster formation temperature ∼220 K. Antiferromagnetic order has been observed at T(N) ∼ 6 K. Ba(4)Sn(1.1)Mn(2.9)O(12) is a semiconductor with a transport activation energy of 0.61 eV.
