Historically, the first and most studied example of this effect is the linear magnetoelectric effect.Mathematically, while the electric susceptibility and magnetic susceptibility describe the electric and magnetic polarization responses to an electric, resp. a magnetic field, there is also the possibility of a magnetoelectric susceptibility which describes a linear response of the electric ...
There have been reports of large magnetoelectric coupling at room-temperature in type-I multiferroics such as in the "diluted" magnetic perovskite (PbZr 0.53 Ti 0.47 O 3) 0.6 –(PbFe 1/2 Ta 1/2 O 3) 0.4 (PZTFT) in certain Aurivillius phases. Here, strong ME coupling has been observed on a microscopic scale using PFM under magnetic field among ...
Magnetic couplings can transmit power via a linear motion, rotary motion, or helical compound motion (a combination of linear motion and rotary motion). The combination of these transmission methods and different mechanical geometry can realize a wide variety of orderly motion in three-dimensional space.
Because of their magneto electric coupling, multiferroic materials are of interest in applications where there is a need to control magnetism through applied electric fields. Such applications include tunnel magnetoresistance (TMR) sensors, spin valves with electric field tunable functions, high-sensitivity alternating magnetic field sensors ...
In this way, such properties as the electric polarization, orbital magnetization, anomalous Hall conductivity, and orbital magnetoelectric coupling can be expressed in terms of Berry phases, connections, and curvatures. [5] [7] [8]
To obtain the tensorial optical metric, medium properties such as permittivity, permeability, and magnetoelectric couplings must first be promoted to 4-dimensional covariant tensors, and the electrodynamics of light propagation through such media residing within a background space-time must also be expressed in a compatible 4-dimensional way.
Media that exhibit magnetoelectric coupling and that are anisotropic (which is the case for many metamaterial structures [48]), are referred to as bi-anisotropic. [49] [50] Four material parameters are intrinsic to magnetoelectric coupling of bi-isotropic media.
MESO devices operate by the coupling of the magnetoelectric effect with the spin orbit coupling. [3] Specifically, the magnetoelectric effect will induce a change in magnetization within the device due to an induced electric field, which can then be read out by the spin orbit coupling component which converts it into an electric charge.
