Abstract:

Using the measurements of the magnetic susceptibility and magnetization we have investigated the magnetic properties of Mn-intercalated MnxTiSe2 compounds having a hexagonal crystal structure of a quasi-two-dimensional type. Unlike other 3d-transition metals, intercalation of Mn ions between Se-Ti-Se tri-layers increases the c-parameter of the lattice. All compounds of MnxTiSe2 exhibit a paramagnetic behavior above similar to15 K. The effective magnetic moment mu(eff) of Mn in MnxTiSe2 is found to be less than mu(eff) for the free Mn2+ ion. In a low-temperature region a spin-glass or cluster-glass behavior depending on the intercalant concentration is observed. The paramagnetic Curie temperature theta(p) takes negative values and decreases monotonically with increasing x, while the freezing temperature shows non-monotonous change at the intercalation. The obtained results are discussed taking into account Mn 3d-Ti 3d hybridization effects and variations of intralayer and interlayer exchange interactions with intercalation. (C) 2004 Elsevier B.V.
