| Abstract: | BiFeO3,one of very few multiferroics with a simultaneous coexistence of ferroelectric and antiferromagnetic at room temperature,has potential applications in memory devices,sensors and spintronics devices et al.In the temperature range of 4-1100K,BiFeO3 bulk single crystals are investigated by Raman scattering,and discussed in combination with the magnetic ordering and the structural phase transition. |
