Large magnetoelectric response and its origin in bulk Co-doped BiFeO3 synthesized by a stirred hydrothermal process

Low enegry Raman spectra showing that Co-doping in BiFeo3 results in the disappearance of the peak modes associated with the presence of the spin modulation responsible for the inhibition of stronger magentic response. Once suppressed a 8 times stronger magentoelectric coefficient αME is achieved.179
