摘要：
The relaxation of the initial magnetic permeability has been measured in polycrystalline LixFe3-xO4 samples, with x ranging from 0 to 0.5, by means of the magnetic disaccommodation (DA) technique. We have found that there is no abrupt transition for a given composition, but there is a progressive modi. cation of the characteristic relaxation processes of magnetite. These results have been interpreted on the basis of the increasing amount of Li ions in the spinel lattice and hence, the resulting modi. cations on their proximities. (c) 2007 Elsevier B.V.
