Anomaly in structural noncentrosymmetry around TNn bulk and nanoscale BiFeO3 Goswami, S, Bhattacharya, D, Iles, G, Ghosh, B, Prytuliak, A, Malard, B, Das, G, Ouladdiaf, B and Chatterji, T 2013, 'Anomaly in structural noncentrosymmetry around TNn bulk and nanoscale BiFeO3', Powder Diffraction, vol. 28, no. 2, pp. 94-105. Document type: Journal Article Collection: Journal Articles Title Anomaly in structural noncentrosymmetry around TNn bulk and nanoscale BiFeO3 Author(s) Goswami, S Bhattacharya, D Iles, G Ghosh, B Prytuliak, A Malard, B Das, G Ouladdiaf, B Chatterji, T Year 2013 Journal name Powder Diffraction Volume number 28 Issue number 2 Start page 94 End page 105 Total pages 12 Publisher International Centre for Diffraction Data Abstract Using high resolution powder neutron diffraction data, we show that there is a distinct anomaly in the structural noncentrosymmetry around the magnetic transition point TN for bulk and nanoscale BiFeO3. It appears that the structural noncentrosymmetry - which gives rise to the ferroelectric polarization - is suppressed anomalously by ~1% (of the average noncentrosymmetry at above the magnetic transition) in the bulk sample and by ~12% in the nanoscale sample as the magnetic transition is approached from higher temperature. This observation shows that the multiferroic coupling improves in the nanoscale sample which is expected to brighten the application prospects of nanoscale BiFeO3 in nanospintronics-based sensor devices.
