“…Small induced magnetic moments on the Ni and Sn atoms in the ferromagnetic state collapse in the DLM state, and their effect is neglected here. The experiment also shows negligible residual resistivity at T =0 K for Ni 2 MnSn [25] which simplifies comparison with the calculated value. On the contrary, e.g.…”

“…A simpler approach can be used for systems in which the MSRO effects are weak, like, e.g., in some Heusler alloys [14] or bcc-Fe. For example, an empirical expression ρ(T ) = ρ o + AT + CT 2 is obeyed reasonably well in a number of Heusler alloys [25]. It should be pointed out that this is an empirical fact and not a rigorous theory, and that in other cases, e.g.…”

Abstract. The spin-disorder resistivity (SDR) of transition metal ferromagnets (Fe, Co, Ni), rare-earth ferromagnet Gd, and Ni 2 MnSn Heusler alloy is determined from first principles. We identify the SDR at the Curie temperature with the residual resistivity of the corresponding system evaluated in the framework of the disordered local moment (DLM) model which has the zero spin-spin correlation function. The underlying electronic structure is determined in the framework of the tight-binding linear muffin-tin orbital method which employs the coherent potential approximation (CPA) to describe the DLM state. The DLM fixed-spin moment approach is used in the case when the DLM moment collapses. The electronic structure of hcp-Gd is determined using both the open core and LDA+U approaches. The Kubo-Greenwood approach is used to estimate the resistivity. For bcc-Fe and Ni 2 MnSn alloy we shall also estimate the temperature-dependent of resistivity below the Curie temperature using a semiempirical approach. Calculations are compared with the supercell Landauer-Büttiker approach developed recently as well as with available experimental data and overall good agreement is obtained.

Spin Disordered Resistivity of the Heusler Ni₂MnGa-based Alloys

Electrical resistivity of the selected Heusler off-stoichiometric (NiCo)2Mn(GaIn) alloys was studied in a wide range of temperature and magnetic field. A step-like change of resistivity (∆ρ ≈ 24 µΩcm) was detected in the offstoichiometric Ni1.85Mn1.21Ga0.94 alloy at temperature of martensitic structural transition. This ∆ρ is much more significant than one in the stoichiometric Ni2MnGa alloy. In the case of the off-stoichiometric (NiCo)2Mn(GaIn) alloys, an enormous change of resistivity, ∆ρ ≈ 200 µΩcm, accompanies the structural transition. Simultaneously, the maximum of the spin disordered resistivity ρ sd (T ) of austenite phase of the alloys is slightly dependent on composition of the alloy and vary from ≈ 30 µΩcm up to ≈ 45 µΩcm, in good agreement with theoretical calculations. Due to high sensitivity of the structural transition temperature of the alloys to magnetic field, the very pronounced magnetoresistance effects have been observed in the studied alloys.
