Abstract:

A neutron diffraction study of the crystalline structure and magnetic state of LaMnO3+delta samples with different deviations from oxygen stoichiometry has been made at 4.2 K. It is shown that annealing at reduced oxygen pressure is accompanied by transformation of the magnetic structure from ferromagnetic, with magnetic moments parallel to the b axis, to antiferromagnetic, with the wave vector k=0 and the moments along the a axis (space group Pnma). A comparison of experimental with expected Mn ion moments suggests that magnetic order does not extend throughout the sample volume. Part of the Mn ions form magnetic clusters similar to 20 Angstrom in size. (C) 1999 American Institute of Physics. {[}S1063-7834(99)02201-7].
