Electron transport properties of amorphous (${\mathrm{ZR}}_{0.64}$${\mathrm{Ni}}_{0.36}$${)}_{1\mathrm{-}\mathit{x}}$${\mathrm{Al}}_{\mathit{x}}$ alloys

Measurements of the electrical resistivity ρ(T), thermopower S(T), and Hall coefficient $R_H$ for a series of rapidly quenched Zr-Ni-Al alloys are reported for concentrations from x=0 to 0.25. The resistivity is large (ρ≊200 μΩ cm) and increases with Al content as does $R_H$, which is positive for all concentrations studied. The thermopower is positive but decreases in magnitude with Al concentration. A consistent qualitative explanation of the concentration dependence of ρ, $R_H$, and S is suggested.
