The electrical resistivity of amorphous Ni80−xMxB16Si4 alloys, M standing for any of the 3d transition metals, was studied in the temperature range ∼2–950 K. The resistivity versus M plots (at constant x) yield typical double-peaked curves, with a minimum at Mn. The origin of this resistivity behaviour is discussed. All the samples show a resistivity minimum, probably due to Kondo effect, at Tmin, which is strongly composition dependent. Negative temperature coefficients of resistivity found about room temperature for several alloys are the consequence of Tmin lying well above room temperature for those alloys.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
