The development of three-dimensional nanowire structures made from magnetic materials is a promising area of research for next-generation information storage technologies. Advanced synthetic methodologies have enabled the fabrication of highly ordered arrays of magnetic nanowires, significantly enhancing data recording densities. The fundamental mechanism of writing and reading data in such devices relies on the magnetization reversal process. However, magnetostatic interactions between individual nanowires can present challenges for reliable data storage. This study investigates how geometric parameters influence the magnetic properties of nanowires. Specifically, it examines segmented configurations with alternating magnetic/nonmagnetic layers, as well as non-segmented structures composed solely of magnetic material. Using first-order reversal curve analysis, we systematically explore how varying the aspect ratio (diameter-to-length ratio) of identical magnetic materials affects magnetostatic interactions during magnetization. Our findings demonstrate that precise tuning of the nanowire aspect ratio enables the magnetic properties to be modified as required, with this modification directly correlating with the magnitude and nature of internal magnetic interactions. These results provide valuable insights for optimizing the design of magnetic nanowire-based storage devices, paving the way for enhanced performance in future data storage applications.
