Abstract
- We report the preparation and characterization of vanadium substituted four-layer Aurivillius compound Bi<subscript>5</subscript>Fe<subscript>1.5</subscript>V<subscript>0.5</subscript>Ti<subscript>2</subscript>O<subscript>15</subscript> using spin coating method. Ferroelectricity in the prepared films are confirmed from the well saturated polarization vs electric field (P-E) loops having remnant polarization (2 P<subscript>r</subscript>) around 12.94 µC/cm<superscript>2</superscript> at room temperature. In addition, low temperature P-E measurements show a decrease in P<subscript>max</subscript> and 2 P<subscript>r</subscript>, which is attributed to the stabilization of defect dipole complexes and domain pinning, as seen in bismuth-based ferroelectrics. Additionally, this decrease in polarization is accompanied by an increase in imprint, confirming the presence of defect dipoles manifested as internal fields. [ABSTRACT FROM AUTHOR]
