Room temperature magnetoelectric coupling in single crystal Bi2Fe4O9 nanotubes grown within an anodic aluminum oxide template

Single crystalline Bi2Fe4O9 nanotubes with diameter ~100nm were synthesized within the pores of Anodic Aluminium Oxide template by vacuum injection technique. The material showed ferroelectric hysteresis and weak ferromagnetism. The latter is ascribed to uncompensated spin at the nanotube surface. A...
