摘要：
Single-crystalline BiFeO3 nanorods have been prepared with a hydrothermal method under magnetic fields. The nanorods exhibit enhanced magnetization in comparison with the microcubes synthesized without the magnetic field. The nanorods display anomalous Raman behaviors, i.e., frequency shift of E-1, A(1)-1 and A(1)-2 modes and an enhanced intensity of the A(1)-2 mode, meaning there is magnetic anisotropy in the BiFeO3 lattice. The enhanced magnetization and anomalous Raman change are mainly attributed to the modulated spin structure from the distorted lattice caused by the magnetic field.
