| 中文摘要 | The transmission electron microscopy observations of the charge ordering (CO) which governs the electronic polarization in LuFe2O4-delta clearly show the presence of a remarkable phase separation at low temperatures. Two CO ground states are found to adopt the charge modulations of Q(1) = (1/3, 1/3, 0) and Q(2) = (1/3 + epsilon, 1/3 + epsilon, 3/2), respectively. Our structural study demonstrates that the incommensurately Q(2)-modulated state is chiefly stable in samples with relatively lower oxygen contents. Data from theoretical simulations of the diffraction suggest that both Q(1)- and Q(2)-modulated phases have ferroelectric ordering. The effects of oxygen concentration on the phase separation and electric polarization in this layered system are discussed. (C) 2010 Elsevier Ltd. All rights reserved. |
