Abstract: | Abstract Magnetic and neutron studies are done about iron-intercalated titanium diselenide, FexTiSe2 with 0<x≤0.5. A neutron diffraction measurement shows that Fe-atoms are located between neighboring selenium layers. Magnetic measurements show that FexTiSe2 are spin glasses for 0. 15≤x≤0.22 and antiferromagnets for 0.25≤x≤0.5. T-x magnetic phase diagram is determined. This diagram is slightly different from that determined by Huntley et al. The difference may be caused by a formation of Fe-clusters in their samples. The x-dependence of the parameters of paramagnetic susceptibilities is determined. |
