STUDY OF ELECTRIC AND MAGNETIC PROPERTIES OF AMORPHEAL METAL ALLOYS BY MYOSSBAUER SPECTROSCOPY

Abstract

The master's thesis is devoted to the study of the electrical and magnetic properties of amorphous iron-based alloys by the methods of Miossbauer spectroscopy, as well as experimental data on the study of the short-range order of iron atoms by the methods of Miossbauer spectroscopy and ferromagnetic resonance. The main models of amorphous structures and methods for their construction are considered. The classification of amorphous alloys according to the size and impact resistance of defects in the atomic structure, i.e., according to the characteristic regions, topology, and chemical composition of the amorphous phase, differs significantly from the indices. Amorphous alloys were considered as systems with a spatial self-organizing defect structure consisting of a multilevel correlation between density and chemical composition. The density of states of the distribution of internal areas of amorphous alloys is determined. We analyzed 4 samples (Fe80B20 Fe76B20Nb4 Fe74B20Nb6 Fe70B20Nb10) of Mössbauer spectra formed in our amorphous band, their spectral analysis and diffraction patterns obtained with a diffractometer. All measurements were carried out at room temperature. In addition, the electrical and magnetic parameters of the samples were determined using an LCR meter.
