Abstract

Pure BiFeO³ (BFO), Eu doped BFO (BEF), and Nd doped BFO (BNF) multiferroic films were prepared by pulsed laser deposition on Pt/Ti/SiO ²/Si substrates. XRD analysis revealed that the films had the rhombohedral structure with doping-induced lattice distortion. The Eu and Nd doping significantly improved the dielectric, ferroelectric, and ferromagnetic properties of the BFO films. Saturated hysteresis loops were observed in BEF and BNF films with remnant polarization of 37 μC/cm² and 60 μC/cm², respectively. The magnetization was demonstrated with remnant magnetization of 0.10 emu/cm³ and 0.60 emu/cm³ for the BEF and BNF films, respectively. The improvements and mechanism of different element doping on the properties of the BFO films were discussed.
