Abstract

From an extrapolation of previously reported thermoelectric power (TEP) data of Zr-Ni glasses for Ni contents below 70 at.%, large negative TEP values were expected for alloyswith about 90 at.% Ni. By contrast, in the present work, large positive values (as high as+8U.V /K in some cases) were obtained at room temperature for melt-quenched Zr10Nigo, Zr9Ni95and HfnNi89alloy ribbons either in the amorphous or crystalline state. The TEP wasfound to be positive and to increase monotonously from 4.2 K to 320 K with a broad maximumaround room temperature. These anomalously large positive thermopower data are suggested tobe explained based on ideas developed for crystalline solid solution alloys of Ni with earlytransition metals.
