We know multiferroic property is the combination of the at least two ferroic properties among- (anti)ferromagnetic, ferroelectric and ferroelastic. In multiferroics, electric field controls magnetization as a result magnetoelectric coupling is found in that materials. How do this coupling originate? Is there any references?
Dear Kumar,
there are so many references on this topic. Better you can read some electromagnetic books apart from this, so many research review papers are available on this. G Sreenivasan from Oakland University, R. Ramesh from USA, W.C. Nan from China, and some other great people have done much work on this.
Go Through those papers. I too have done some work on this. Better read some of my papers. You will get the information. Wishing you good luck.
Electric-field control of magnetization is converse magneto-electric effect (CME).According to spin current model that has explained induced P in
various spiral-or helimagnets P= Aeij*( Si*Sj)
where Si and Sj denote spins at neighboring sites i and j respectively. P- Elecrtical polarization.

Dear Researcher You may go through these papers to have clear understanding of M-E coupling and control in both qualitative as well as quantitatively:
1. Article Multiferroics: Different Ways to Combine Magnetism and Ferro...
2. Nature Materials volume6, pages13–20 (2007)
3. 10.1126/science.1113357
4. Nature Materials volume7, pages425–426 (2008)
5. https://physics.aps.org/articles/pdf/10.1103/Physics.2.20
First try to understand that how do ferroic orders are arsing or combing in a single phase materials.They may be due to either charge,spin,orbital or lattice .Coupling among themselves are governed by very basic physics laws or symmetry breaking.
coupling and control may be of two types as commonly mentioned in literature Type-I or Type -II.
