Here we address the Magnetoimpedance effect and demonstrate that it can help us in the study of the dynamics of magnetization in nanostructured systems. Specifically, we explore an accessible, robust approach to calculate the Magnetoimpedance phenomenon in thin film systems. To verify the robustness of our theoretical approach, we produced a ferromagnetic thin film of Ni81Fe19, an alloy widely known in the magnetism community, and performed its quasi-static and dynamic magnetic characterization. Our results, in addition to revealing the agreement between theory and experiment, provide a simple way to describe ferromagnetic systems and their interactions with static and alternating magnetic fields, simultaneously. Through investigating the magnetic properties of different systems, we can produce a wide range of sensor devices for various technological applications.
