| Abstract: | Magnetization measurements have been made on 3d transition-metal intercalation compounds of MxTiS2 (M = V, Cr, Mn, Fe, Co and Ni; 0 ⩽ x ⩽ 1) at 4.2, 77 and 300 K in static fields up to 20 kOe and in pulsed fields up to 160 kOe. The ac magnetic susceptibility measurements in dc fields have also been made for FexTiS2. We have identified various types of magnetic phases in MxTiS2, such as paramagnetic, spin-glass, cluster-glass or mictomagnetic, and ferromagnetic ones, depending on the kind of guest 3d metals and their concentrations. Magnetic properties of these materials can be understood in terms of an itinerant or band picture rather than a localized or rigid band model. |
