| titleOfInvention | A ferromagnetic/antiferromagnetic heterojunction with exchange bias effect and its preparation |
| abstract | The invention belongs to the field of magnetic materials, and more specifically relates to a ferromagnetic/antiferromagnetic heterojunction with exchange bias effect and its preparation. The multiferroic heterojunction has a MFe 2 O 4 /BiFeO 3 bilayer film structure, in which MFe 2 O 4 is used as a ferromagnetic layer, BiFeO 3 is used as an antiferromagnetic layer, and M is Ni or Co. The inverse spinel ferrite MFe 2 O 4 (M=Co, Ni) with a high Curie temperature is selected as the ferromagnetic material, and the Curie temperature of MFe 2 O 4 is close to the Neel temperature of BiFeO 3 . It has excellent ferromagnetism at room temperature and has great potential to increase the cut-off temperature of the system. The coercive field H C of the multiferroic heterojunction provided by the present invention, CoFe 2 O 4 /BiFeO3 bilayer film=15.84KOe, and also observed obvious exchange bias field (H EB (3K)=- 142.5Oe). |
