采用脉冲激光沉积法在铂/钛/二氧化硅/硅衬底上制备了Nd0.1Bi0.9FeO3/Bi2FeMnO6双层薄膜。BiFeO_3是反铁磁体，而BiMnO_3是铁磁体，-Mn-O-Fe-O-Mn-是有序的，这将导致薄膜中的铁磁相互作用。薄膜表现出典型的铁磁性质，转变温度为440K，室温铁电极化也被观察到，表明该薄膜是一种很有前途的RT多铁性。
Nd0.1Bi0.9FeO3/Bi2FeMnO6 bilayered films were deposited on Pt/Ti/SiO2/Si substrate by pulsed laser deposition method. BiFeO3 is antiferromagnet while BiMnO3 is ferromagnet, the ordering of –Mn–O–Fe–O–Mn– is expected, which will induce the ferromagnetic interation in the film. The film shows typical ferromagnetic properties with the transition temperature of Tc of 440 K. The room temperature (RT) ferroelectric polarization was also observed, suggesting that the film is a promising RT multiferroism.
