Hall effect in amorphous magnetic materials — METGLAS 2826 and 2826B

Hall effect measurements on the ferromagnetic amorphous materials, Metglas 2826 and 2826B, indicate that they are rather similar to crystalline soft magnetic materials. The extra-ordinary Hall coefficient R_s is found to be 1.4 × 10⁴?² (m³/As), where, ?, is the electrical resistivity, and is in reasonable agreement with the predictions of theory. On the other hand, though unexpected, the ordinary Hall coefficient in all the amorphous alloys we have studied turns out to be of the order of 7 × 10^?10 (m³/As).
