Investigation of the electronic characteristics of Ni3 (Fe,Ti) and Ni3 (Mn,Ti) alloys

The anomalous Hall (R_s) and the Nerst-Ettingshausen (Q_S) constants are measured for hardened Ni₃ (Fe, T_i) and Ni₃ (Mn, Ti) alloys. Scattering by phonons is detected, con tributing primarily to R_S as compared to scattering by magnetic inhomogeneities. Based on the positive signs of R_g and Q_S, it is concluded that 3d holes wi th antiparallel spin make the main contribution to the conductivity. A model is proposed for the electronic structure of the alloys studied.DeceasedTranslated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 6, pp. 59—63, June, 1981.
