Magnetic susceptibility of titanium diselenide intercalated with copper

Abstract

The temperature dependence of the magnetic susceptibility of Cu xTiSe 2 polycrystalline samples has been measured. The electron density of states near the Fermi level N(E F) in the Pauli model of paramagnetism has been calculated and discussed. The concentration dependences of the density of states N(E F) and the unit cell parameter in the direction perpendicular to the layers in Cu xTiSe 2 correlate with the concentration of centers V-Ti-Cu and Cu-Ti-V (V is the vacancy). © 2012 Pleiades Publishing, Ltd.
