| Abstract: | Abstract Raman scattering spectra and magnetic susceptibility are measured in intercalation compounds FexNbS2 (0.159≤x≤0.325). A strong modification of Raman spectra is observed in a sample with x=0.239 (～ 0.25) which is accompanied by 2a × 2a structural change and antiferromagnetic ordering. Some correlations between magnetic ordering (antiferromagnetic or spin glass) and structural change are also discussed for wide range of Fe contents x. |
