The magnetic structure of BFO is antiferromagnetic with the G-type spin ordering below the Néel temperature and this G-type antiferromagnetic structure has been modulated by a cycloidal spin with a large period of wavelength λ=620±20 Å. Synthetic antiferromagnets (often abbreviated by SAF) are artificial antiferromagnets consisting of two or more thin ferromagnetic layers separated by a nonmagnetic layer. Dipole coupling of the ferromagnetic layers results in antiparallel alignment of the magnetization of the ferromagnets. Antiferromagnetism plays a crucial role in giant magnetoresistance, as had been discovered in 1988 by the Nobel prize winners Albert Fert and Peter Grünberg (awarded in 2007) using syntheti… hor.hu
