ABSTRACT
BiFeO3 is the prototypical multiferroic and one of the few with both (anti)ferroic ordering temperatures above 300 K. While its magnetic and ferroelectric properties and their coupling have been investigated intensely, offering opportunities in spintronics, little is known concerning its optical properties and their coupling to the ferroic orders. For applications in the microwave range, we report on the integration of BiFeO3 onto low permittivity substrates. Such integrated films show good ferroelectric and optical properties consistent with those of films grown on SrTiO3 substrates. Prospects for the use of BiFeO3 in optical applications are discussed.
