Tracking how the spin cycloid in BFO evolves with electric field and temperature

AFM order in BFO was first detected by neutron diffraction and was classified as Type G. However, the spins are not perfectly antiparallel; there is a spatial-modulated spin...反铁磁有序（Antiferromagnetic, AFM）在铋铁氧体（BFO）中首次通过中子衍射被检测到，并被归类为G型。然而，其自旋并非完全反平行，存在空间调制的自旋……
