Abstract
The values for the normal Hall coefficient R_0, electrical resistivity ρand the room-temperature coefficient of resistivity αfor ten amorphous NiBSi alloys with metalloid concentration ranging from 20 to 39 at% are reported. R_0and αcontinuously decrease with increasing metalloid content or, for the fixed metalloid content, with increasing silicon concentration and αchanges sign for ρ≳140 μΩcm. The values of the Fermi wave vector deduced from R_0(within the framework of the free electron model) indicate that the transport properties of Ni–metalloid alloys can be interpreted in terms of the Ziman–Faber theory. The concentration dependence of R_0indicates a significant charge transfer from metalloid atoms to the conduction band.
