MAGNETIC-PROPERTIES OF 3D TRANSITION ELEMENT INTERCALATED COMPOUNDS MSTISE(2)

Polycrystalline samples of M(x)TiSe(2) with M=V, Cr, Mn, Fe, Co, Ni an d Cu were prepared. All the compounds showed paramagnetic behavior at 4.2 K less than or equal to T less than or equal to 300 K. Effective p aramagnetic moment mu(eff) of all the M-atoms are much smaller than io nic values, suggesting that the M-states are strongly hybridized with the TiSe2-band. Cr Mn, Fe and Co may be in the high-spin states. The m u(eff)-data are compared with those of TyTiS2 with T=V: Mn, Fe, Co. Ni and Cu in our previous studies and with the band calculation results of Motizuki et al., and discussions are done about the electronic stat es of T- and M-atoms. It is suggested that the S-3p states are hardly hybridized and the Se-Sp states are slightly hybridized with a Ti-3d e psilon non-bonding band.
