Excitation of Spin Waves in an In-Plane-Magnetized Ferromagnetic Nanowire Using Voltage-Controlled Magnetic Anisotropy

The authors propose applying a microwave-frequency electric field to a ferromagnetic/dielectric nanowire to excite propagating spin waves in the wire, providing a path to energy-efficient spintronic signal processing. This scenario should not be confused with the ``parallel parametric pumping'' discussed previously, as the mechanism of parametric coupling is completely different: via out-of-plane dynamic magnetization, not precession ellipticity.
