LOW TEMPERATURE RESISTIVITY STUDIES IN Cr CONTAINING AMORPHOUS ALLOYS Fe-Ni-Cr-Mo-Si-B.

Abstract

Resistivity data on Fe//4//0// minus //x/////2Ni//4//0// minus //x/////2Cr//xMo//2Si//1//0B//8 samples with x equals 0,1,3,4,5 in the temperature region 7 K-300 K have been reported. A minimum is observed in the resistivity as a function of temperature at a temperature T//m//i//n varying between 20 K to 80 K for the five samples. Attempts are made to fit the data with a sum of a T**2 term and various functional forms predicted for the negative temperature coefficient region.
