Summary

The results of transport properties study, as a function of temperature of gold-chromium thin film alloys obtained by controlled coevaporation show that: 1) electrical resistivity presents two types of variations, when the atomic chromium concentration is lower or higher 30%. In the first case, it is linear, in the second case, the variation is growing then falling, in relation with the magnetic structure of the samples; 2) thermoelectric power of the alloy including 38 at. % chromium goes from positive values to negative values when temperature increases; 3) Hall coefficient which is stable from 100 to 573 K changes of sign for the 65 at. % chromium concentration.
