磁场作用下PMN-PT／CFO的磁电效应研究
Research of the magnetoelectric effect of PMN -PT/CFO in magnetic field
摘要
Abstract
In terms of elasticity mechanical theory model ,the magnetoelectric voltage coefficient formula is estab-lished ,using the magnetostrictive properties of CoFe2 O4 (CFO) in the magnetic field ,we obtain the changing re-lations of Pb(Mg1/3 Nb2/3 ) O3 -PbTiO3 (PMN-PT )/CFO magnetoelectric voltage coefficient changing with the magnetic field and other parameters .The magnetoelectric voltage coefficient is also studied as the function of the Magnetic field intensity 、PMN-PT volume fraction v、interface coupling coefficient k and PMN -PT dielectric constant in magnetic field .The results show that the magnetoelectric voltage coefficient increase firstly ,then gradually decreases to zero with the increase of PMN -PT volume fraction and magnetic intensity ;the magneto-electric voltage coefficient strongly depends on the interface coupling coefficient ,which will largely reduce mag-netoelectric effect ;Meanwhile ,Magnetoelectric effect has a certain frequency characteristic ,with the increase of frequency ,which increase gradually and reaches stability .关键词
