title = "Local weak ferromagnetism in single-crystalline ferroelectric BiFeO 3",
abstract = "Polarized small-angle neutron scattering studies of single-crystalline multiferroic BiFeO3 reveal a long-wavelength spin density wave generated by ∼1° spin canting of the spins out of the rotation plane of the antiferromagnetic cycloidal order. This signifies weak ferromagnetism within mesoscopic regions of dimension 0.03 microns along [1{\=1}0], to several microns along [111], confirming a long-standing theoretical prediction. The average local magnetization is 0.06μB/Fe. Our results provide an indication of the intrinsic macroscopic magnetization to be expected in ferroelectric BiFeO3 thin films under strain, where the magnetic cycloid is suppressed.",
