| 摘要 | Monoclinic Fe3-xCrxSe4 nanostructures (0 <= x <= 2.5) were synthesized using a high-temperature solution chemical method. With increasing the Cr doping, the peak positions in the X-ray diffraction (XRD) patterns of Fe3-xCrxSe4 nanostructures slightly shifted to lower 2 theta. values due to the changes in lattice parameters. Expansions in the unit cell volumes of Fe3-xCrxSe4 nanostructures (x > 0.3) may have been responsible for enhancing the ferromagnetic (FM) interaction between magnetic ions, which resulted in a significant increase in the Curie temperature (T-C) from 331 K for Fe3Se4 to 429 K for FeCr2Se4, distinctly differing from the magnetic properties of the corresponding bulk materials. A room-temperature coercivity (H-C) analysis showed an obvious increase from 3.2 kOe for Fe3Se4 to 12 kOe for Fe2.3Cr0.7Se4 nanostructure, but gradually decreased upon further increasing the Cr content. |
