Enhanced optical properties and the origin of carriers transport in BiFeO/TiO heterostructures with 109 domain walls
Hong-Jian Feng, Bi Duan, Jinshou Tian +1
The absorption performance in the BiFeO/TiO bilayer film prepared by simple sol-gel method has been significantly improved in the ultraviolet and visible-light region, comp…
Photovoltaic effect in BiFeO3/TiO2 heterostructures tuned with epitaxial strain and an electric field
Hong-Jian Feng, Artem R. Oganov
The photovoltaic effect in the BiFeO3/TiO2 heterostructures can be tuned by epitaxial strain and an electric field in the visible-light region which is manifested by the enhancemen…
Electric-field switching magnetization and spin transfer in ultrathin BiFeO3 film
Hong-Jian Feng
First-principles density-functional theory calculations show switching magnetization by 90 degree can be achieved in ultrathin BFO film by applying external electric-field. Up-spin…
Magnetism and electronic properties of BiFeO3 under lower pressure
Hong-Jian Feng
Ab initio calculations show an antiferromagnetic-ferromagnetic phase transition around 9-10 GPa and a magnetic anomaly at 12 GPa in BiFeO3. The magnetic phase transition also invol…
The role of Coulomb and exchange interaction on the Dzyaloshinskii-Moriya interaction(DMI) in BiFeO3
Hong-Jian Feng
Ab initio calculations show that the Dzyaloshinskii-Moriya interaction(DMI)and net magnetization per unit cell in BiFeO3 are reduced when U is increasing from 0 to 2.9 eV, and inde…
The reversal of magnetization driven by the Dzyaloshinskii-Moriya interaction(DMI) in perovskite Bi2FeMnO6
Hong-Jian Feng
Ab initio calculations show that the coupling between antiferrodistortive(AFD) distortions and magnetization in perovskite Bi2FeMnO6 is prohibited to make magnetization rotate as o…
