摘要

The voltage control of magnetism has attracted intensive attention owing to the abundant physical phenomena as-sociated 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 energy-efficient,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 de-vice applications.
