Abstract

We calculate the profile of both magnetization and polarization of a PML-typemagnetoelectric multiferroics which allow the magnetization of sub-lattices to be canted.  Thecalculation is started by deriving the Landau energy density and followed by solvingsimultaneously three equilibrium equations which respect to polarization, magnetization andcanting angle.   It is predicted that magnetoelectricity give rise to a “bump” in polarization profile. It is also calculated that the application of a magnetic/an electric field will also influence thepolarization/magnetization of the material.

Keywords:  multiferroics, magnetization and polarisation
