Voltage control of ferromagnetic resonance and spin waves

Abstract

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.

“…The compounds could also be used to detect H 2 S in HeLa cells when cells were pre-treated with NaHS. 52…”

“…Strain engineering and charge doping are two widely used methods to introduce new phases and effectively tune magnetic properties of the 2D structures. [19][20][21][22][35][36][37][38][39] For instances, on one hand, in strain engineering, Lucas et al have reported the strain-tunable magnetic anisotropy energy (MAE) in 2D SL-CrX 3 (with X = Cl, Br, and I), [36] and on the other hand, charge doping is applied to tune the magnetic properties of SL-CrI 3 . [19] To our knowledge, up to now, the influences of strain and charge doping on the magnetic properties of SL-CrBr 3 have not been discussed in detail in the present literatures.…”

Effect of interface magnetization depinning on the frequency shift of ferromagnetic and spin wave resonance in YIG/GGG films*

“…If the spin precessions are not uniform, the propagation of collective precessions in a ferromagnet forms spin waves (the magnons are the quanta of spin waves). [1,2] The conventional complementary metal-oxidesemiconductor (CMOS) based electronics can no longer meet the requirements of high processing speed, small size, and low power consumption, one of the alternative methods having the ability to satisfy the above requirements is magnonics. [3][4][5][6][7][8][9][10] The aim of magnonics is to use spin waves to transmit, store, and process the information.…”
