Formation, structure and magnetic properties of Nd3Fe 26.8-xCoxV2.2 compounds

Journal Article


Abstract


  • Single-phase Nd3Fe26.8-xCoxV 2.2 compounds with Nd3(Fe,Ti)29-type structure have been synthesized successfully for x = 0-12; and their structures and magnetic properties were investigated by x-ray diffraction and magnetic measurements. The Curie temperature increases drastically with increasing Co content from 500 K for x = 0-847 K for x = 12. All the compounds show a spin reorientation transition as temperature decreases. Spin reorientation temperature T sr shows an increasing tendency with the exception of a minimum at around x = 6. Saturation magnetization increases monotonically with increasing Co content, which can be understood in terms of a rigid band model. The anisotropy field at 5 K decreases with increasing Co content. All the compounds show easy-plane-type anisotropy at room temperature and the series of the compounds is not suitable for permanent materials.
