High value of ferroelectric polarization in BFO nanorods

Significantly high value of polarization is obtained in multiferroic Bismuth Ferrite (BFO) in form of nanorods protruding out. These were developed on porous Anodised Alumina (AAO) templates using wet chemical technique. Diameters of nanorods vary in the range from 10–100 nm. The high value of polarization is attributed to the nanostructure. There is no leakage current in P-E loop observed at various fields and frequencies.
