Abstract:Polycrystalline BiFeO3 (BFO) films were prepared on Pt / TiO2 / SiO2 / Si substate by using magnetic-field-assisted 90° off-axis pulsed laser deposition (PLD). We have successfully obtained polycrystalline BFO films owing to a high deposition rate derived by a confinement of the plume under a magnetic field. The obtained polycrystalline BFO films have a droplet-free surface morphology and a columnar-like microstructure. A room-temperature ferroelectric hysteresis loop is obtained, and at same time, the remanen… Show more
