Multiferroic and in-plane magnetoelectric coupling properties of BiFeO3 nano-films with substitution of rare earth ions La3+ and Nd3+

Single-phase multiferroic BiFeO3 and Bi0.9(La/Nd)0.1FeO3 (doped with rare earth ions La3+ and Nd3+) films grown on (111)-Pt/Ti/SiO2/Si substrate were prepared via sol-gel method and a subsequent rapid thermal process. The phase composition, microstructure, ferroelectric, dielectric, ferromagnetic properties were investigated, and meanwhile, the in-plane magnetoelectric (ME) coupling effects of the films were reported and studied for the first...
