Pressure dependence of the room-temperature resistance ofCo100−xZr

Abstract

We report on measurements at room temperature of the pressure dependence of the resistance of the amorphous alloys, Co~Do "Zr"and Fe&po "Zr". The pressure coefficient of resistance ap is small and negative, becoming more negative with increase in the Zr concentration. For a given Zr concentration, np is sensibly the same whether Co or Fe makes up the alloy. Indeed, this same behavior is seen in Ni]00 &Zr" and Cu~oo "Zr", suggesting that it is only the Zr component in these alloys that plays a role in the pressure variation of the resistance.
