Almeida-Thouless Line in BiFeO3: Is Bismuth Ferrite a mean field spin glass?
Manoj K. Singh, Ram S. Katiyar, W. Prellier +1
Low-temperature magnetic properties of epitaxial BiFeO3 thin films grown on (111)-SrTiO3 substrates have been studied. ZFC and FC magnetization curves show a large discrepency begi…
Magnetoelastic-magnetoelectric phase transitions in multiferroic BiFeO3
S. A. T. Redfern, C. Wang, J. W. Hong +2
Our measured dielectric constant and mechanical response of multiferroic BiFeO3 indicate four phase transitions below room temperature. Features correlate with those reported at 50…
One-magnon (electromagnon) light scattering in BiFeO3 single crystals
Manoj K. Singh, Ram S. Katiyar, J. F. Scott
We observed Raman scattering from magnon in frequency range from 10 to 65 cm-1 in BiFeO3 single crystals at cryogenic temperatures; the temperature dependence of the magnon frequen…
