Mixed lithium-transition metal oxides LiFe<sub>1−<i>x</i></sub>Co<sub><i>x</i></sub>O<sub>2</sub> (0≤<i>x</i>≤1) have been studied by powder neutron diffraction in the temperature range 1.5-100 K and at room temperature. The low-temperature data analysis of the high-flux neutron diffraction patterns reveals an antiferromagnetic arrangement with a propagation vector <i>k</i>=[0 0 ½ ]. The value obtained for the magnetic moment of Fe<sup>3+</sup> ions at 1.5 K, <i>μ</i><sub>Fe<sup>3+</sup></sub>=3.9 <i>μ</i><sub>B</sub>, is in good agreement with the value deduced from magnetization data and is also consistent with the high spin state of Fe<sup>3+</sup> ion. The crystallographic structure was determined by both X-ray and high-resolution neutron diffraction measurements.< Leer menos
