Epitaxial growth of BiFeO3-Ba(Cu1/3Nb2/3)O3 thin films deposited by pulsed laser deposition |
| 초록 |
Multiferroic thin films with composition 0.9BiFeO3-0.1Ba(Cu1/3Nb2/3)O3 were epitaxially grown by pulsed laser deposition on SrRuO3(001)/SrTiO3 (000) substrate0.9BiFeO3-0.1Ba(Cu1/3Nb2/3)O3, which is assumed to be morphotropic phase boundary (MPB), that showed superior dielectric, ferroelectric and magnetic properties in our study on polycrystalline films. The structures of epitaxially grown films were characterized by means of XRD. From P–E measurements, samples exhibited typical ferroelectric hysteresis loops and large remnant polarization, whose value is much larger than those of pure BFO film. The enhancement of dielectric, ferroelectric, magnetic properties was attributed to the structural distortion induced by the BCN addition and the high physical stress effect. |
