Ni doping dependent dielectric, leakage, ferroelectric and magnetic properties in Bi7Fe3-xNixTi3O21 thin films
Abstract
Bi7Fe3-xNixTi3O21 thin films were prepared by chemical solution deposition on Pt/Ti/SiO2/Si substrates. The Ni doping effects on the dielectric, leakage, ferroelectric and magnetic properties were investigated. Coexistence of ferroelectric and ferromagnetic properties at room-temperature was observed in the Bi7Fe2NiTi3O21 thin film with a remnant polarization 2Pr of 36.4 μC/cm2 and a remnant magnetization 2Mr of 3.9 emu/cm3. The dielectric and leakage properties were discussed in detailed. The results will provide important information to explore single-phase multiferroic materials.
