Resumen
Neutron diffraction techniques have been used to determine the magnetic structure of Fe in monoclinic alpha -Li3Fe2(PO4)(3). Rietveld analysis of the room temperature powder diffraction pattern confirms the monoclinic structure of the sample and is in agreement with previous studies. At low temperatures a paramagnetic to antiferromagnetic transition is observed at T-N = 30.0 K. Our analysis shows that at T = 4 K the two inequivalent Fe sites have antiparallel magnetic moments that are aligned along the a-axis. The average magnetic moment, gS = 5.0 mu (B) indicates homogeneous Fe3+ (S = 5/2). (C) 2001 Elsevier Science B.V. All rights reserved. 234 3 401 408
