Excitation of propagating spin waves in an in-plane magnetized ferromagnetic strip by voltage-controlled magnetic anisotropy

Voltage-induced excitation and control of spin waves (SWs) propagating in thin ferromagnetic (FM) films and nanostructures became a hot topic in modern spintronics. The use of electric field (or voltage) to control propagating SWs has significant advantages in comparison with the well-developed techniques of SW control using magnetic field and current, as it allows one to significantly decrease the total energy losses in SW-based signal processing devices and improves the compatibility of these devices with conventional silicon microelectronics. The excitation and control of SWs using electric field could be achieved by means of various magnetoelectric effects in FM materials and structures. Among these effects the recently discovered effect of the voltage-controlled magnetic anisotropy (VCMA) is one of the most perspective due to its high efficiency, linearity and applicability at the nanoscale.
