Electrical and magnetic properties ofPd2MnIn,Pd2MnSn,Cu2MnAl, andCu2NiSn Heusler alloys

Abstract

Results are described for the field and temperature dependences of the electrical resistivity, Hall effect, and transverse magnetoresistance of ferromagnetic, antiferromagnetic, and diamagnetic Heusler alloys. The experiments cover the approximate ranges 2-300 K and 0-4.8\ifmmode\times\else\texttimes\fi{}${10}^{6}$ ${\mathrm{Am}}^{\ensuremath{-}1}$, with supporting measurements of the magnetization in the ranges 4-300 K and 0-1.6\ifmmode\times\else\texttimes\fi{}${10}^{6}$ ${\mathrm{Am}}^{\ensuremath{-}1}$. A qualitative interpretation is given of the general behavior of electron transport and leads to information about the microscopic scattering mechanisms involved, but some features remain unexplained.
