ELECTRICAL AND MAGNETIC-PROPERTIES OF TITANIUM DISELENIDE INTERCALATED WITH COBALT

This paper discusses experimental studies of the temperature dependenc e of the magnetic susceptibility, electrical conductivity, and Seebeck coefficient of the compounds CoxTiSe2 (0.1 less than or equal to x le ss than or equal to 0.5), along with the structural behavior exhibited by these compounds. For Co0.5TiSe2, the observed temperature dependen ce of the magnetic susceptibility is characteristic of an antiferromag net with a Neel temperature of 510 K. The data obtained on the structu ral characteristics and physical properties of the intercalated phases are interpreted using a model that assumes the formation of bands of localized states near the Fermi level.
