In general we discuss about three ferroic phase such as ferromagnetic (magnetic field and B-H loop), ferroelectric (electric field and P-E loop) ferroelastic (stress and S-E loop) phases. Multifferroic materials shows more than one ferroic phase (combinations).
Magnetoelectric materials are multiferroic showing magnetic field induced polarization and electric field induced magnetization (coupling between magnetization and polarization with their respective electric and magnetic fields).
All magnetoelectric are multiferroics but all mutiferroics are not magnetoelectrics.
The definition of multiferroic is clear. While the concept of magnetoelectric is confusing, maybe for me. As reported by Eerenstein et al (nature, 2006, 442, 759-765, doi:10.1038/nature05023), magnetoelectric coupling is an independent phenomenon.
Question:materials that show magnetodielectric/magnetocapacitance could be considered as magnetoelectrics?
Thank you for all. According to this graph displayed in Dr. CZhang, not all magnetoelectric are multiferroics which included in Dr. Kumar.
Magnetoelectric are those where magnetic fields can change the polarization and electric field can change the magnetization i.e there is electro-magnetic coupling but its not necessary that there is any kind of 'ordering' is there.
While multiferroics can be the combination of any of the : ferromagnetic, ferroelectric, ferroelastic.
Thus not all magnetoelectrics are multiferroics nor all multiferroics are magnetoelectrics.
The common set of these two are: magnetoelectric multiferroics.
Thank you very much Glory V. Umoh and Siddhi Mukta
I think that multiferroics are a special case of magnetoelectrics
