The hysteresis curves of a material are capable of showing the relationship between the magnetization and the applied magnetic field. These curves are crucial to understanding the magnetic properties of ferrites, which are widely used in electronic applications, such as transformers and inductors. In this work, hysteresis curves of barium and strontium ferrites, in varying proportions, were adjusted using the Hyperbolic Tangent Model. This model demonstrated a good capacity for adjusting the observed hysteresis curves, which present a characteristic sigmoidal aspect. The parameters obtained from the adjustment allowed a better understanding of the physical and magnetic properties of the analyzed samples. The Hyperbolic Tangent Model proved to be effective not only due to the high correlation coefficient achieved, but also due to its ability to reflect the nuances of the magnetic properties under different conditions. The results obtained may have significant implications for the application of these ferrites in magnetic and electronic devices, since understanding their fundamental properties is crucial to optimizing the performance of these materials in different contexts. In short, the work highlights the importance of mathematical modeling as a tool for elucidating the magnetic characteristics of barium and strontium ferrites. The results suggest that the Hyperbolic Tangent Model is a promising approach for future investigations into magnetic materials consisting of ferrites.
