Magnetoelectric (ME) xLa(0.6)Ca(0.4)MnO(3)-(1-x)Bi0.6Nd0.4TiO3 composite thin films with x = 0.3, 0.4, and 0.5 were fabricated on Pt/Ti/SiO2/Si(100) substrates by a chemical solution deposition method. The well-defined ferroelectric loops are observed. The Pr values are 11.2, 12.8, and 13.9 mu C/cm(2) under the condition of about 350 kV/cm electric field for the composite films with x=0.3, 0.4, and 0.5. The composite films exhibit typical magnetic hysteresis loops, as well as remnant magnetizations. ME effect which is dependent on H-bias is observed. The results show that the films exhibit both good ferroelectric and magnetic properties, as well as a ME effect.
