Are magnetoelectric energy harvesting devices suitable for self-powered devices?

Energy harvesting devices based on the magnetoelectric (ME) coupling effect have promising prospects in the field of self-powered devices due to their advantages of small size, fast response, and low power consumption.

What are the order parameters of a magnetic system?

Thus, the material hosts two order parameters: a macroscopic magnetization (M = Msub,1 + Msub,2) and a Néel vector (L = Msub,1 − Msub,2). The larger magnetic anisotropy of this system increases the processional frequency and, thus, reduces the switching time.

What is a magnetoelectric material?

Magnetoelectric material exhibit interconnections of magnetic and electric field. ME applications can be classified as direct coupling and converse coupling. There are various ME devices including sensor, antenna and microwave devices. ME devices show better performance and the potential to be miniaturized.

Can magnetoelectric and multiferroic materials improve energy-delay performance of spin-based devices?

Instead, the use of magnetoelectric and multiferroic materials has been proposed as a pathway to markedly improve energy-delay performance of spin-based devices.

Where does magnetoelastic energy come from?

The magnetoelastic energy, \ ( {B}_ {mnkl}\), originates from changes in the spin–orbit coupling of occupied states of the electronic structure due to the mechanical distortion. The other key materials consideration is the strength of the stiffness tensor components as the elastic energy will compete with the magnetoelastic energy.

What are the applications of multiferroic magnetoelectric materials?

The application of multiferroic magnetoelectric (ME) materials, which realize the mutual coupling (ME coupling effect) of ferroelectric ordering and magnetic ordering (Figure 1A ), in the fields of magnetic sensors, 17 - 20 spintronics, 21 - 24 data storage, 25 - 29 and energy harvesting 29 - 32 can be further broadened.
