Abstract
A thermocouple which consists of two parts of a Fe77.5Si7.5B15 wire-an amorphous part and a crystalline part-which is crystallized by passin g a oc current through it, supplies a thermoelectromotive force that d epends linearly, up to 470 K in the first approximation, on the juncti on temperature. The amorphous part is electropositive compared to the crystalline part. The value of the thermoelectric power depends on the evolution of the crystallization process which is simultaneously stud ied by measurements of the magnetic induction and of the electrical re sistance. The quantitative determination of the thermo emf is a sensit ive method for the study of the crystallization process in ribbon- and wire-shaped amorphous materials.
