A ferroelectric Bi3.25Sm0.75Ti2.98V0.02O12 (BSVT) film and colossal magnetoresistive La0.67Sr0.33MnO3 (LSMO) film heterostructure on Si with excellent performances of both ferroelectric and ferromagnetic properties at room temperature was fabricated by the pulsed laser deposition method. Saturated magnetizationmagnetic field hysteresis loops and polarizationelectric field loops proved the materials compatibilities in keeping their own intrinsic properties of LSMO and BSVT in the heterostructure. The remanent polarization (2Pr) of the BSVT is 56 ÃÂÃÂÃÂõC cm-2 at an applied electrical voltage of 11 V. Fatigue measurements show a 25% decrease in remanent polarization after 106 read/write cycles but no further changes afterwards.
