Abstract

The electronic, magnetic, and transport properties of Fe-intercalated 2H-TaS2 have been investigated by means of the Korringa-Kohn-Rostoker (KKR) method. The nonstoichiometry and disorder in the system have been accounted for using the coherent potential approximation (CPA) alloy theory. A pronounced influence of disorder on the spin magnetic moment has been found for the ferromagnetically ordered material. The same applies for the spin-orbit-induced orbital magnetic moment and magnetocrystalline anisotropy energy. The temperature dependence of the resistivity of disordered 2H-Fe0.28TaS2 investigated on the basis of the Kubo-Streda formalism in combination with the alloy analogy model has been found in very satisfying agreement with experimental data. This also holds for the temperature-dependent anomalous Hall resistivity rho(xy)(T). The role of thermally induced lattice vibrations and spin fluctuations for the transport properties is discussed in detail.
