Structural, electrical and magnetic properties of (110)-oriented BF-BZT-ST Films

Highly (110)-oriented BiFeO3-Bi(Zn/Ti)O3-SrTiO3 thin films were prepared on conductive Nb doped SrTiO3 substrates by pulsed laser deposition. The results demonstrate that the films show a pure perovskite phase with R3c symmetry. The films have a low dielectric loss, and a typical multiferroics character, possessing both of ferroelectric and ferromagnetic properties. The reduced dielectric loss is attributed to thermodynamic stabilization and charge compensation mechanisms in the BiFeO3 system. The remnant polarization (Pr) and the remnant magnetization (Mr) are ~ 46.2 μC/cm2 and ~ 4.6 emu/cm3 respectively.
