Abstract

Soft magnetic properties of amorphous alloys are determined by their structure, which strongly depends on their manufacturing method. Alloys obtained in the form of conventional amorphous alloys (tapes) are cooled with a much higher rate than the material obtained in the form of tiles by the injection casting method. The cooling rate and production method determines the type and number of structural defects created in the volume of produced samples. The paper presents an indirect method for the analysis of structural defects and their effect on the magnetic properties of studied alloys. Basing on initial magnetization curve analysis in the area of so-called approach to ferromagnetic saturation was found that point defects were forming in the samples in the form of tapes. The magnetization process of tiles were influenced by the presence of conglomerates of point defects called quasidislocation dipoles.
