Hall effect in Ni-rich FexNi80-xB18Si2amorphous alloys

Abstract
The Hall resistivity of amorphous FexNi80-xB18Si2 alloys (x=0, 5, 8, 10, 12 and 15) has been measured in the paramagnetic region. Except for x=0 these alloys are ferromagnetic with Curie temperatures TC0=-(1+or-0.1)*10-10 m3 A-1 s-1 was roughly independent of x. The anomalous Hall coefficient Rs was positive, a factor of one hundred bigger, and it increased with x. The results for R0 and Rs are compared with those for similar systems and discussed in terms of the recent theoretical models.
