Room temperature spontaneous exchange bias in BiFeO3 micro/nano powders synthesized by hydrothermal method

Significant Enhancement of the Visible Light Photocatalytic Properties in 3D BiFeO3/Graphene Composites

“…BFO submicron cubes were synthesized by a simple hydrothermal method [57,58], and all the chemicals were purchased from Aladdin. Bi(NO 3 ) 3 •5H 2 O and Fe(NO 3 ) 3 •9H 2 O crystals were weighed in a molar ratio of 1:1, and then dissolved in 50 mL of deionized water by magnetic stirring.…”

Magnetism and Raman Investigations of Hydrothermally Reduced Graphene Oxide-Incorporated α-Fe2O3 Nanocomposites: The Role of Temperature-Dependent Charge Transfer-Induced Interfacial Interactions

“… , It is basically due to the varying response of interfacial spins for positive and negative field directions. Experimentally, this effect has been observed in various systems including nanoparticles/nanocomposites, polycrystalline oxides, ceramics, alloys, etc. − Several factors can contribute to such effects in FRGO. The interfacial exchange coupling between the sp 3 units of PRGO and spins of NPs (as both are magnetically dissimilar anisotropic systems) strongly enhances the perpendicular magnetic field anisotropy (PMI) at the interface, giving rise to asymmetry. , The coexistence of multiple magnetic phases across newly developed interfaces in NC can result in a complicated interaction energy landscape with symmetry breaking across the particle–matrix interface.…”

Influence of using different types of microreactors on the formation of nanocrystalline BiFeO3

“…There are several methods for synthesis of bismuth orthoferrite nanoparticles, for example, solution combustion [12][13][14][15][16][17][18][19][20], hydrothermal synthesis [21][22][23][24][25][26][27], and solid phase synthesis [28][29][30][31][32][33][34][35]. However, obtaining single-phase nanocrystalline powders based on bismuth orthoferrite still causes difficulties [28,[36][37][38][39][40].…”
