MAGNETIC STUDIES OF THE HOMOGENEITY OF FERRIMAGNETIC AMORPHOUS FILMS

The temperature dependence of the torque moment, galvanomagnetic Hall effect and magnetoresistance of ferrimagnetic amorphous films prepared by sputtering GD+Co were investigated in the temperature region which included a compensation temperature T-kappa. Anomalies in the depende nces of all three characteristics were observed and these were connect ed with an inhomogeneity in the chemical composition of the films. An approximate method of estimating the film chemical homogeneity was pro posed, based on an analysis of the films magnetic properties
