Abstract
Polarized small-angle neutron scattering studies of single-crystalline multiferroic BefeO3 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 [110}, to several microns along [111], confirming a long-standing theoretical prediction. The average local magnetization is 0.06 υΒ/Fe. Our results provide an indication of the intrinsic macroscopic magnetization to be expected in ferroelectric BFO thin films under strain, where the magnetic cycloid is suppressed.Citation
