Hall effect and magnetization of amorphous FeZr alloys

Abstract

We present measurements of the Hall coefficients of a series of amorphous Fe1−xZrx alloys (0.57≤x≤0.80, x=0.11) and correlate these with magnetization data on several samples. For x≤0.65 the alloys are ferromagnetic with large positive spontaneous Hall components. For x>0.71 the paramagnetic alloys exhibit small positive Hall coefficients. We suggest that this latter positive result arises from the spontaneous side jump contribution in the paramagnetic regime.
