Magnetic layers composed of soft ferromagnetic alloys as novel magnetic materials have been attracted great attention in recent years. These materials are suitable candidates for use in electronic circuits especially at high frequency microelectronics elements and magnetic sensors. In this paper, electronic transport properties under application of alternative current of magnetic thin wires with cylindrical geometry toward analysis of the magnetoimpedance (MI) effect will be studied. Our aim is to solve the Maxwell and Landau-Lifshitz equations simultaneously in cylindrical coordinate. Furthermore, we in addition are aiming investigation of magneto-dynamical equations of the mentioned structures under application of alternative magnetic fields with microwave frequencies. The main focus will be on the effect of exchange interaction term on the MI response which results in spin wave in resonance and anti-resonance effect addition to the wave propagation in such structures. Finally, based on the important parameters the MI response will be analyzed for application in magnetic sensors and microelectronics elements.
