Abstract:

A polycrystalline sample of Ba4Mn3O10 has been prepared and characterized by X-ray diffraction (290 K), neutron diffraction (290, 80, 5 K) and magnetometry (5 less than or equal to T(K) less than or equal to 1000). At 290 K the compound is paramagnetic and isostructural with Ba4Ti2PtO10. Mn3O2 trimers, built up from MnO6 octahedra, are linked through common vertices to form corrugated sheets perpendicular to the gamma-axis of the orthorhombic unit cell (Space group Cmca, a = 5.6850(1), b = 13.1284(1), c = 12.7327(1) Angstrom); Ba atoms occupy the space between the layers. On cooling the magnetic susceptibility shows a broad maximum at similar to130 K, and a sharp transition at 40 K. Neutron diffraction has shown that long-range anti ferromagnetic order is present at 5 K but not at 80 K, although magnetometry at 5 K has revealed a remanent magnetization (0.002 mu(B) per Mn) which is below the detection limit of the neutron experiment.
