摘要：

Layered LiFe1-xCoxO2 compounds have been studied by powder-neutron diffraction in the temperature range 1.5 100 K and at room temperature. The Bragg reflections of LiFe1-xCoxO2 can he indexed in the R-3m space group. At low temperatures, for x < 0.6 samples, an A-type AF structure is observed with a propagation vector k = [00(1)/(2)] and a magnetic moment mu(3b) (Fe3+) = 3.9mu(B). (C) 2002 Elsevier Science B.V.
