Reduced Coercive Field in BiFeO₃ Thin Films Through Domain Engineering

Abstract

The coercive field is an important parameter for applications of lead-free multiferroic BiFeO3 with the highest values of polarization and transition temperature. We report here the lowest ever observed coercive field and optimum polarization values in BiFeO3 thin films using domain engineering approach. The measurements performed under ambient conditions over a wide frequency range demonstrate the application potential of this unique ferroelectric material.
