Abstract:

Using the measurements of the susceptibility and magnetization in steady and pulsed magnetic fields and under applied hydrostatic pressure we have investigated the magnetic properties of Cr-intercalated CrxTiSe2 compounds having a hexagonal crystal structure of a quasi-two-dimensional type. It has been found that the effective magnetic moment mu (eff) of Cr changes nonmonotonously with Cr-content. The mu (eff)(x) dependence correlates with the change in the interlayer distance at the intercalation which is attributed to the change of the localization degree of the chromium 3d-electrons. The intercalation lends to changes of the magnetic state of CrlambdaTiSe2 from the Pauli paramagnetism at x = 0 to the claster-glass behavior at 0.25 less than or equal tox less than or equal to0.33 and then to the antiferromagnetic order in Cr0.5TiSe2. The last compound exhibits a held-induced spin-flip transition below the Neel temperature T-N = 38 K due to the very low ratio between the interlayer and intralayer exchange interaction (w(2) / w(1) approximate to 5.4 x 10(-3)). The applied hydrostatic pressure decreases the Neel temperature with a rate dT(N) / dp = -0.19 K/kbar. The interlayer exchange interaction was found to be more sensitive to the Cr-Cr distance than the intralayer one. (C) 2001 Elsevier Science B.V. All rights reserved.
