Magnetic properties of Cr-intercalated TiSe2

Influence of the Mn intercalation on magnetic properties of TiSe2

“…As it follows from estimations in Ref. [7], the diamagnetic contribution to the total magnetic susceptibility of M x TiSe 2 should not change significantly upon intercalation. Therefore, the change of χ 0 may be associated mainly with the concentration dependence of the Pauli contribution χ p .…”

“…Ab initio calculation of the magnetic moment per Mn in the compound Mn 1/3 TiSe 2 has given the value of 3.35 B only [9]. Moreover, the high-field magnetization measurements performed at low temperatures for some intercalated compounds Cr 0.5 TiSe 2 [7], Cr x TiTe 2 [13] and M x TiS 2 (M = Fe, Mn, Co, Ni [14]) have shown that the magnetic moment per intercalated guest atom in saturation, µ S , is appreciably lower than that expected from the localized electron model. These data indicate the itinerant character of the M 3d-electrons.…”

“…In particular, the compounds Fe x TiSe 2 (x = 0.25, 0.33, 0.5) have an antiferromagnetic order below corresponding Néel temperatures of 62, 95 and 129 K [5]. The antiferromagnet-like behavior was found to exist in Cr 0.5 TiSe 2 below T N = 38 K [7].…”

“…The intercalation of some 3d-metals in M x TiX 2 leads to appearance of the different magnetic states depending on the type and concentration of M-atoms as well as on the parent TiX 2 matrix. While the compounds TiX 2 are Pauli paramagnets, the intercalated compounds M x TiX 2 exhibit a spin-glass or cluster-glass behavior at the low concentration of M-atoms and antiferromagnetic or ferromagnetic order at the high M-content [4,5,7]. In particular, the compounds Fe x TiSe 2 (x = 0.25, 0.33, 0.5) have an antiferromagnetic order below corresponding Néel temperatures of 62, 95 and 129 K [5].…”

Preparation of Nanocomposite Magnetic Compounds Based on Layered Semiconductors by Means of Electrochemical Intercalation in a Gradient Magnetic Field

“…The interaction of intercalated * corresponding author; e-mail: chimsp@ukrpost.ua atoms with atoms of the lattice can lead to its deformation, changed conductivity, appearance of different magnetic states, decrease of the effective magnetic moment of inserted magnetic atoms. At present as the most studied layered compounds intercalated with 3d-metals we can consider dichalcogenides of transition metals TX 2 (T = Ti, Mo, W; X = S, Se) [16][17][18][19][20]. The preferable technique for their obtaining is high-temperature thermal treatment of a mixture of µm-sized powders of an intercalant and a layered compound.…”
