Ito, and Guangyong Xu We present neutron inelastic scattering measurements of the low-energy phonons in single crystal BiFeO 3 . The dispersions of the three acoustic phonon modes (LA along [100], TA 1 along [010], and TA 2 along [11̅ 0]) and two low-energy optic phonon modes (LO and TO 1 ) have been mapped out between ...
