Abstract:
The magnetization, Hall effect, and resistivity of Heusler alloys Co$_{2}$Fe$Z$ (where $Z$ = Al, Si, Ga, Ge, In, Sn, and Sb are $s$- and $p$-elements) have been studied at $T$ = 4.2 K in magnetic fields $H\le$ 100 kOe. In strong fields ($H>$ 20 kOe), magnetization can be described by the Stoner model. The normal $R_{0}$ and anomalous $R_{S}$ Hall effect coefficients have been determined. The coefficient $R_{S}$ is positive for almost all the studied alloys and represents a “linearly quadratic” resistivity function incorporating linear and quadratic terms. The constant $R_{0}$ is negative for most alloys, and its absolute value is two or three orders of magnitude smaller than for $R_{S}$. The magnetoresistivity of the studied alloys does not exceed several percent and may be both positive and negative for different specimens.
