FINEMET Micro-ribbons: The Experimental Identification of the Object

The experimental investigation of the FINEMET samples, such as \({\text {Fe}}_{73.5}{\text {Cu}}_{1}{\text {Nb}}_{3}{\text {Si}}_{13.5}{\text {B}}_{9}\), is presented. The analysis of the chemical elements, the micro-ribbons are made of, is discussed. The experimental data for the specific susceptibility dependent on temperature, the X-ray fluorescent spectroscopy, the X-ray structural analysis, the ferromagnetic resonance spectrums in the field of super high frequency, the amplitude–frequency characteristics in the rectangular resonator in one-mode regime, the complex impedance as the function of frequency of the applied voltage, and the mechanical vibrations in the soft magnetic materials are provided. The problem of developing a comprehensive complex analytical method for the soft magnetic micro-ribbons is raised.
