Abstract

In this study, the First Order Reversal Curve (FORC) method was employed to investigate the magnetic domain behavior and analyze the magnetic properties of hard (cobalt ferrite) and soft (nickel ferrite) spinel ferrites. The samples were prepared using standard methods, and their structural and magnetic characteristics were examined using analyses such as X-ray diffraction (XRD) and vibrating sample magnetometry (VSM). Using FORC diagrams, the coercivity distribution, magnetic interactions, and magnetization reversal behavior of the samples were analyzed. The results indicated significant differences between hard and soft samples in terms of magnetic characteristics such as the FORC distribution, distribution peaks, and irreversible regions. This study demonstrates that FORC analysis is a powerful tool for gaining deeper insight into the magnetic domain structures and internal interactions in nanostructured magnetic materials.
