The effect of intercalation by 3d elements on the structure and physical properties of titanium diselenide MxTiSe2 (M = Cr, Fe, Co)

The dependences of the structural parameters and the electrical and magnetic properties of titanium diselenide, intercalated by chromium, iron, and cobalt on the intercalant concentration and temperature were studied experimentally. The possibility of the involvement of d electrons in the formation of interlayer covalent bonds in relation to the 3d-shell filling of intercalated ion is discussed.
