Abstract

Measurements under hydrostatic pressure of the electrical resistivity of (Ni _0.36Nb _0.24Zr _0.40) _100-xH _x (x = 9.8, 11.5, and 14) glassy alloys have been made in the range of 0-8 GPa and 0.5-300 K. The resistivity of the (Ni _0.36Nb _0.24Zr _0.40) ₈₆H ₁₄ alloy changed its sign from negative to positive under application of 2-8 GPa in the temperature range of 300-22 K, coming from electron-phonon interaction in the cluster structure under pressure, accompanied by deformation of the clusters. In temperature region below 22 K, the resistivity showed negative thermal coefficient resistance by Debye-Waller factor contribution, and superconductivity was observed at 1.5 K.
