The Influence of Temperature and Magnetic Field on the Magnetic Structure of Domains of the Fe5Ga6Gd2YZr Crystal

This study examines the X-ray fluorescence spectroscopy results and Raman scattering spectroscopy results of a Fe₅Ga₆Gd₂YZr crystal. A quantitative analysis of the spectral data was conducted. Raman spectroscopy and X-ray fluorescence (XRF) analysis were employed to obtain spectral peaks, which were used to study the structural features and elemental composition of the sample, respectively, as part of its physical analysis. The graphs clearly show the intensities of the characteristic lines of the elements such as Fe, Ga, Gd, Y, and Zr. Additionally, the temperature dependence of domain structure ordering in the Fe₅Ga₆Gd₂YZr crystal was investigated over the range of 134–296 K. The study demonstrated that temperature-induced changes in the domain structure led to the emergence of magnetic hysteresis. It was observed that as the temperature rises, the separation between domain boundaries gets wider. Moreover, the effect of an external magnetic field on the domain structure was studied in the magnetic induction interval of 0–4.6 mT. Comparative analysis of domain images under increasing and decreasing magnetic field conditions clearly illustrates the presence of remanent magnetization within the crystal.
