Abstract

Nd_0.1Bi_0.9FeO₃ /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 T_c of 440 K. The room temperature (RT) ferroelectric polarization was also observed, suggesting that the film is a promising RT multiferroism.
