Preparation method of CoFe2O4 magnetic thin film

The invention provides a method for adopting pulse laser to deposit a CoFe2O4 magnetic thin film on a Pb(Mg1/3Nb2/3)O3-PbTiO3(PMN-PT) single-crystal substrate. The CoFe2O4 magnetic thin film with dense and uniform thin film particles and obvious magnetoelectric effect is prepared, the obvious in-pla...

Beschreibung
Zusammenfassung:	The invention provides a method for adopting pulse laser to deposit a CoFe2O4 magnetic thin film on a Pb(Mg1/3Nb2/3)O3-PbTiO3(PMN-PT) single-crystal substrate. The CoFe2O4 magnetic thin film with dense and uniform thin film particles and obvious magnetoelectric effect is prepared, the obvious in-plane anisotropy is obtained, when an in-place magnetic field is in different directions of the thin film, the coercive field of the thin film changes obviously, direct-current voltage and alternating-current voltage are adopted for regulating the change of magneto-optical kerr signals, and the resultshows that the heterojunction of the thin film shows the obvious inverse magnetoelectric coupling effect induced by strain. 种在Pb(MgNb)O-PbTiO(PMN-PT)单晶基片上采用脉冲激光沉积CoFeO磁性薄膜的方法，制备薄膜颗粒致密、均匀且磁电效应明显的钴铁氧体铁磁薄膜，获得了明显的面内各向异性，外加面内磁场沿着薄膜不同方向时，薄膜的矫顽场产生了明显的变化，分别采用直流和交流电压调控磁光克尔信号的变化，结果表明薄膜异质结展示了明显的应变诱导的逆磁电耦合效应。
