The voltage control of magnetism has attracted intensive attention owing to the abundant physical phenomena associated with magnetoelectric coupling. More importantly, the techniques to electrically manipulate spin dynamics, such as magnetic anisotropy and ferromagnetic resonance, are of great significance because of their potential applications in high-density memory devices, microwave signal processors, and magnetic sensors. Recently, voltage control of spin waves has also been demonstrated in several multiferroic heterostructures. This development provides new platforms for energyefficient, tunable magnonic devices. In this review, we focus on the most recent advances in voltage control of ferromagnetic resonance and spin waves in magnetoelectric materials and discuss the physical mechanisms and prospects for practical device applications.

We show that using maskless photolithography and the lift-off technique patterned yttrium iron garnet thin films possessing ultra-low Gilbert damping can be accomplished. The films of the 70 nm thickness were grown on (001)-oriented gadolinium gallium garnet by means of pulsed laser deposition and exhibit high crystalline quality, low surface roughness and effective magnetization of 127 emu/cm 3 . The Gilbert damping parameter is as low as 5 × 10 −4 . The obtained structures have well-defined sharp edges which along with good structural and magnetic film properties, pave a path in the fabrication of high-quality magnonic circuits as well as oxide-based spintronic devices.Yttrium iron garnet (Y 3 Fe 5 O 12 , YIG) has become an intensively studied material in recent years due to exceptionally low damping of magnetization precession and electrical insulation enabling its application in research on spin-wave propagation 1-3 , spin-wave based logic devices 4-6 , spin pumping 7 , and thermally-driven spin caloritronics 8 . These applications inevitably entail film structurization in order to construct complex integrated devices. However, the fabrication of high-quality thin YIG films requires deposition temperatures over 500C 6,[9][10][11][12][13][14][15][16][17][18] leading to top-down lithographical approach that is ion-beam etching of a previously deposited plain film whereas patterned resist layer serves as a mask.Consequently, this method introduces crystallographic defects, imperfections to surface structure and, in the case of YIG films, causes significant increase of the damping parameter. [19][20][21] Moreover, it does not ensure well-defined structure edges for insulators, which play a crucial role in devices utilizing
