Nanoscale magnetoelectric coupling in multiferroic BiFeO3 nanowires

Nanoscale magnetoelectric (ME) coupling has been observed in multiferroic BiFeO3 (BFO) nanowires (NWs) synthesized by sol–gel based electrospinning technique. Under externally imposed electric fields these NWs exhibit a systematic evolution of the magnetic domain pattern as established by magnetic f...

Zusammenfassung:Nanoscale magnetoelectric (ME) coupling has been observed in multiferroic BiFeO3 (BFO) nanowires (NWs) synthesized by sol–gel based electrospinning technique. Under externally imposed electric fields these NWs exhibit a systematic evolution of the magnetic domain pattern as established by magnetic force microscopy (MFM), confirming the presence of ME coupling. These results promise one‐dimensional multiferroic BFO NWs as a potential candidate for manipulating magnetism through electric field at the nanoscale and provide great opportunities towards magneto‐electrically tunable multiferroic devices.
