| 摘要: |
Based on the di®erence of hydroxy group con¯guration on di®erent planes of ®-Fe2O3 nanoparticles, using
the special adsorption and coordination of phosphate on the (001) plane of ®-Fe2O3, well-crystallized and well
dispersed ®-Fe2O3 nanodisks with diameter of 150{200 nm and thickness of 40{80 nm were synthesized via
a hydrothermal method. The magnetic properties of synthesized nanodisks were investigated. It was found
that the nanodisks possessed a saturation magnetization (Ms) of 0.38 emu/g, a remanent magnetization
(Mr) of 0.031 emu/g and a coercivity of 452.91 Oe at room temperature. The Mr and coercivity of
synthesized ®-Fe2O3 nanodisks are higher and the Ms is lower than those of other previously reported ®-
Fe2O3 nanostructures. |
