UNSPECIFIED (2001) Short-range order in the topological spin glass (D3O)Fe-3(SO4)(2)(OD)(6) using xyz polarized neutron diffraction. PHYSICAL REVIEW B, 6409 (9). -. ISSN 0163-1829Full text not available from this repository.
We use polarized xyz neutron diffraction to examine the nature of the freezing transition to an unconventional topological spin-glass state in the S=5/2 kagome antiferromagnet (D3O)Fe-3(SO4)(2)(OD)(6). Measurements of the total magnetic scattering cross-section, S(Q), were taken in the momentum-transfer range 0.5 less than or equal toQ less than or equal to2.5 Angstrom (-1) between the temperatures 1.5 and 250 K. The observation of two-dimensional correlations at 250 K, i.e., in excess of 14 times the freezing temperature, is in agreement with predictions of an anisotropy-induced spin-glass freezing transition in an ordered kagome antiferromagnet.
